Weird question wording. I take it should mean that this is a quadratic equation with solutions of x = -5 and x = 8. Then these are the factors: (x+5) and (x-8).
So
(x+5)(x-8) = 0 is the equation because x = -5 and x = 8 can make left-side equal to 0. But we expand so it becomes x² - 3x - 40 = 0

Answer:
Let's simplify step-by-step.
3x2+9x+6−(8x2+3x−10)+(2x+4)(3x−7)
Distribute:
=3x2+9x+6+−8x2+−3x+10+(2x)(3x)+(2x)(−7)+(4)(3x)+(4)(−7)
=3x2+9x+6+−8x2+−3x+10+6x2+−14x+12x+−28
Combine Like Terms:
=3x2+9x+6+−8x2+−3x+10+6x2+−14x+12x+−28
=(3x2+−8x2+6x2)+(9x+−3x+−14x+12x)+(6+10+−28)
=x2+4x+−12
Answer:
=x2+4x−12
