Question

Solve by factoring 6x^2 +13x -28 =0

Answer 1

Answer:

x=4/3 or x=-7/2

Step-by-step explanation:

(3x-4)(2x+7)

Answer 2

Answer:

x=-7/2, x=4/3

Step-by-step explanation:

$6x^2+13x-28=0$

Multiply 6 and -28 to get -168

Find 2 numbers that multiply to 168 but add to 13

They are 21 & -8

Rewrite the equation into:

$6x^2+21x-8x-28=0$

Factor

$3x(2x+7)-4(2x+7)=0$

(3x-4)(2x+7)=0

3x=4

x=4/3

2x=-7

x=-7/2
