What is the solution set for 2x^2+15=-11x

x = {-3, -2.5}

Step-by-step explanation:

Simplifying

3 + x = 0

Solving

3 + x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + x = 0 + -3

Combine like terms: 3 + -3 = 0

0 + x = 0 + -3

x = 0 + -3

Combine like terms: 0 + -3 = -3

x = -3

Simplifying

x = -3

Simplifying

5 + 2x = 0

Solving

5 + 2x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-5' to each side of the equation.

5 + -5 + 2x = 0 + -5

Combine like terms: 5 + -5 = 0

0 + 2x = 0 + -5

2x = 0 + -5

Combine like terms: 0 + -5 = -5

2x = -5

Divide each side by '2'.

x = -2.5

Simplifying

x = -2.5
