Question

5x-(3+2x-2x^2)=2x^2-7x+17

Answer 1

5x-3-2x+2 x²=2 x² -7x+17
5x-2x+7x=17=3
10x=20
x=2.

Answer 2

To solve the equation 5x - (3 + 2x - 2x^2) = 2x^2 - 7x + 17, we can follow these steps:

1. Simplify both sides of the equation by removing parentheses and combining like terms: 5x - 3 - 2x + 2x^2 = 2x^2 - 7x + 17 Rearranging the terms: 5x - 2x + 2x^2 - 2x^2 - 7x = 17 + 3 Combining like terms: 3x - 7x = 20 -4x = 20

2. Divide both sides of the equation by -4 to solve for x: -4x/-4 = 20/-4 x = -5

Therefore, the solution to the equation 5x - (3 + 2x - 2x^2) = 2x^2 - 7x + 17 is x = -5.
