Answer 1

@mathmath333

Answer 2

\(2\times -5=10\\
-9-1=10\)

Answer 3

do u know how to factor ?

Answer 4

I think @mathmath333

Answer 5

ok can u show ur work

Answer 6

What do i factor

Answer 7

lol the equation in the question

Answer 8

oh lol no im not sure how to do it

Answer 9

but u can try , ain't u?

Answer 10

Im just really having a total brain fart right now

Answer 11

so u dont know how to factor

Answer 12

no

Answer 13

ok no problem

Answer 14

how do we do it

Answer 15

\(\Large\ \begin{align} \color{black}{2x^2 -9x-5=0\\
2x^2 -10x+x-5=0\\
2x(x -5)+(x-5)=0\\
(2x+1)(x -5)=0\\~\\
\text{zero product rule}\\~\\
(2x+1)=0~~or~~(x -5)=0\\
x=\dfrac{-1}{2}~~or~~x =5}\end{align}\)
