Question

Choose the factored form of the given equation.

6x^2 + 2x - 8 = 0

(6x- 8)(x+ 1) = 0
(6x+ 1)(x- 8) = 0
(6x+ 8)(x- 1) = 0

Answer 1

ok all the first terms work right? each has \(6x\times x=6x^2\) and all the last terms work because each one gies \(-8\) so the only question is which one gives \(2x\)

Answer 2

= 6x+ 8)(x- 1) = 0 be cause x1=-8 and x2=1 (Viet)

Answer 3

first one
\[6x-8x=-2x\] no
second one
\[-48x+1=-47x\] no
third one
\[-6x+8x=2x\] yes
