#### Solutions

Chapter 1.5, Problem 46E
To determine

## Solve the equations by factoring.

Expert Solution

x=6,2

### Explanation of Solution

Given information:

x2+8x+12=0

Formula used:

Splitting the middle term:- in this method, middle term is splitted in such a way that the product of its part is equal to the product of constant and first terms coefficient.

Calculation:

x2+8x+12=0

Splitting middle term in such a way that product of its part is equal to product of constant and coefficient of first term.

x2+8x+12=0x2+6x+2x+12=0x(x+6)+2(x+6)=0(x+6)(x+2)=0

x=6,2
