4x^4+12x^2+8 solve ✖➖➕➗
Step-by-step explanation:
Simplifying 4x4 + -12x2 + 8 = 0 Reorder the terms: 8 + -12x2 + 4x4 = 0 Solving 8 + -12x2 + 4x4 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '4'. 4(2 + -3x2 + x4) = 0 Factor a trinomial. 4((1 + -1x2)(2 + -1x2)) = 0 Factor a difference between two squares. 4(((1 + x)(1 + -1x))(2 + -1x2)) = 0 Ignore the factor 4.
Subproblem 1
Set the factor '(2 + -1x2)' equal to zero and attempt to solve: Simplifying 2 + -1x2 = 0 Solving 2 + -1x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -1x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1x2 = 0 + -2 -1x2 = 0 + -2 Combine like terms: 0 + -2 = -2 -1x2 = -2 Divide each side by '-1'. x2 = 2 Simplifying x2 = 2 Take the square root of each side: x = {-1.414213562, 1.414213562}
Subproblem 2
Set the factor '(1 + x)' equal to zero and attempt to solve: Simplifying 1 + x = 0 Solving 1 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x = 0 + -1 x = 0 + -1 Combine like terms: 0 + -1 = -1 x = -1 Simplifying x = -1
Subproblem 3
Set the factor '(1 + -1x)' equal to zero and attempt to solve: Simplifying 1 + -1x = 0 Solving 1 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1x = 0 + -1 -1x = 0 + -1 Combine like terms: 0 + -1 = -1 -1x = -1 Divide each side by '-1'. x = 1 Simplifying x = 1
Solution
x = {-1.414213562, 1.414213562, -1, 1}
If a test has 30 questions on it and a student answers 18 of the questions correctly, then what percentage would the student get on the test?
Select ALL equations that are functions.
functions can't be with exponents -
the correct answers are b,c,d
Answer:
These 3:
y = 2, y = 1/2x + 5, y = x
Step-by-step explanation:
Y can't be squared that would give a sideways function, that doesn't pass the vertical line test

A. 20
B. 200
C. 0.2
D. 2,000
Answer:
A. 20Step-by-step explanation:
How many times smaller is 2 × 10⁻⁸ than 4 × 10⁻⁷ ?
Rewrite the numbers with the same power of 10:
2 × 10⁻⁸ and 40 × 10⁻⁸Divide the second number by the first, cancel the powers as they are same:
40/2 = 20Correct option is A
The values are
2×10-⁸ and 4×01^{-7}Divide to find how many times smaller
4/2×10^{-7+8}2(10)20timesA scale drawing of a house shows the house has a height of 11.5 inches. If the scale is 1 inch = 3 feet, how tall is the house in real life?
Group of answer choices
34.5 feet
11.5 feet
3.8 feet
14.5 feet
Answer:34.5
Explanation: So you see that 1 inch is 3 feet and there are 11.5 inches so you put 1 inch 11 times and you'll get 33 and then there is half a inch so half o 3 is 1.5 so if you add 33 plus 1.5 you'll get 34.5.
