Solve each quadratic equation using factoring??
Pleasee help :)

Answer 1

(x+9)(x-4)=0 and then set factors = to 0 to solve

Answer 2

@lisapeajac you just wanna help me with all of them? There's only like 9 left :)

Answer 3

Sure. Factoring is solving a puzzle. What multiplies to give you last number and adds/subtracts to give you the middle number

Answer 4

okay.. umm @lisapeajac 2x^2+9x-5=0

Answer 5

\(\Large{x^2+5x-36=0}\)
\(\Large{=>x^2+9x-4x-36=0}\)
\(\Large{=>x(x+9)-4(x+9)=0}\)
\(\Large{=>(x-4)(x+9)}\)
