solve for x?

anonymous · Answer

factor

jwheele1 · Answer

$$5x ^{2} - 3x -2$$solve for x
Must facor or use the quadratic formula...

jwheele1 · Answer

factor it is

anonymous · Answer

15x^3 - 9x^2 -6x factor using grouping

anonymous · Answer

ohh lol duh ok so you have to factor first. this factors into (5x+2)(x-1)
then x is anything that makes those equal to 0 so x = -2/5 and 1

jwheele1 · Answer

our goal is to fill in these:

( somethign here +/- somethign else here) ( somethign here +/- somethign else here)
when both sets are multiples together you should get your original equation.

Thankyou Kcheung1

jwheele1 · Answer

(5x+2)(x-1)
because 5x times 1x = 5x^2
because 2 * -1 = -2 at the end of your equation
and because 2*x = 2x and 5x * -1 = -5x and 2x -5x = -3x (your middle number)

jwheele1 · Answer

Just for knowledge

(5x+2)(x-1)
set each to zero, and solve each for x
5x+2 = 0
5x = -2
x= -2/5

x-1 = 0
x = 1

answers for x = -2/5 and 1   ....but always plug them back in to be sure
