How many solutions does this equation have ?

x² + 3x -4 = 0
Factor the quadratic equation
Answers
Answer:
(x-1)(x+4)
Step-by-step explanation:
[tex]x^2+3x-4\\x^2-x+4x-4\\x(x-1) 4(x-1)\\(x-1)(x+4)[/tex]
First, find the factors of the constant (number without an x)
The factors of -4 are:
-1, 4
1, -4
2, -2
Looking at these factors find which pair of factors adds up to the middle number (3x)
4 + -1 = 3
Now you can factor this equation. Put x + 4 into one pair of parenthesis and x - 1 into another pair of parenthesis. You do this because you are separating the two factors into two expressions, that when multiplied together, will equal x^2 + 3x - 4
(x+4)(x-1) is the answer
To check this, multiply the two expressions together. You should get x^2+3x-4=0
Stable cost reporting in a manufacturing setting is typically a sign that operations are running smoothly. The accounting department at Rockwell Collins, an avionics manufacturer, analyzes the variance of the weekly costs reported by two of its production departments. A sample of 16 cost reports for each of the two departments shows cost variances of 2.3 and 5.4, respectively. Is this sample sufficient to conclude that the two production departments differ in terms of unit cost variance? Use α = 0.10 (to 2 decimals).

2. It represents [tex]2*2*2*2*2[/tex] and [tex]2*2*2*2*2*2[/tex]
Step-by-step explanation:
1. it would have to be an exponent so 2*2*2 is 8 and 2^3 is also 8
2. it is an exponent so it would basically be multiplying the number times the number/amount of exponents so 2^5= 32 and 2^6=64

If f(x) = 3x + 2 and g(x) = x2 + 1, which expression is equivalent to (f o g)(x)?
Answers
Answer:
(f o g)(x) = 3x^2 + 5
Step-by-step explanation:
(f o g)(x) is a composite function in which g(x) = x^2 + 1 becomes the input to f(x) = 3x + 2.
Write out f(x) = 3x + 2 leaving a blank for each x:
f( ) = 3( ) + 2
Now insert g(x) into the first set of parentheses and x^2 + 1 into the second:
(f o g)(x) = 3(x^2 + 1) + 2, or, after simplification,
(f o g)(x) = 3x^2 + 5
