Solve the following quadratic equation
2x²+7x=15​

Answers

Answer:

x = - 5 ; x = 3/2

Step-by-step explanation:

Start by subtracting 15 from both sides to get to an equation in standard form:  a x^2 + b x + c= 0  so we can use the quadratic formula to solve for "x".

2 x^2 + 7x - 15 = 0

Then:

[tex]x=\frac{-7+/-\sqrt{49-4(2)(-15)} }{4} \\x=\frac{-7+/-\sqrt{169} }{4}\\x=\frac{-7+/-13}{4}\\x =-5\\or\\x=3/2[/tex]

Answers

Answer:

a ) π/2, 4π/3, 3π/2. 5π/3.

Step-by-step explanation:

2 sin t cos t + √3 cos t = 0

cos t ( 2 sin t + √3 ) = 0

Therefore:

cos t = 0,   t 1 = π/2,  t 2 = 3 π/2

or:

2 sin t + √3 = 0

2 sin t = - √3

sin t = - √3 / 2

If a, b are real numbers and 7a + i(3a - b) = 14 - 6i , then find the values of a and b.

Answers

If a, b are real numbers and 7a + i(3a - b) = 14 - 6i, then find the values of a and b. Therefore, the value of a = 2 and the value of b = 12. 3.

The value of the variables 'a' and 'b' of the complex equation will be 2 and 12, respectively.

What is a complex number?

The complex number is the combination of the real part and the imaginary part. Then the complex number is given as a+bi where the value of i is √(-1) and the value of i² is -1.

The equation is given below.

7a + (3a - b)i = 14 - 6i

Compare the real part of the equation, then we have

7a = 14

a = 14 / 7

a = 2

Compare the imaginary part of the equation, then we have

3a - b = - 6

3 x 2 - b = -6

6 - b = - 6

b = 6 + 6

b = 12

The value of the variables 'a' and 'b' of the complex equation will be 2 and 12, respectively.
