3x^2 – X – 2 = 0 how do I solve this by factoring​

Mathematics

Alenkasestr [34]3 years ago
5 0

Answer:

x=-\frac{2}{3} or x=1

Step-by-step explanation:

The given quadratic equation is 3x^2-x-2=0

You split the middle term with 2x-3x to get:

3x^2+2x-3x-2=0

We now factor by grouping to get:

x(3x+2)-1(3x+2)=0

Factor again to get:

(3x+2)(x-1)=0

Apply the zero product principle to get:

(3x+2)=0 or (x-1)=0

This implies that:

x=-\frac{2}{3} or x=1
