Which expression has the same value as the expression 8x^2 + 2x - 6) - (5x^2 - 3x + 2)?

13x^2 - 5x - 4

13x^2 - x - 8

3x^2 - x - 4

3x^2 + 5x - 8

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
