Answer:

The smaller x is -3

The larger x is 4

Step-by-step explanation:

x^2−x−12=0

Factor

What two numbers multiply together to give us -12 and add together to give us -1

-4*3 = -12

-4+3 = 1

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

Using the zero product property

x-4 =0   x+3 = 0

x=4   x=-3

The smaller x is -3

The larger x is 4

Answer:

smaller x=  -3

larger x= +4

Step-by-step explanation:

Factoring the equation x^2−x−12=0

x^2+3x-4x-12=0

x(x+3)-(4x+12)=0

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

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

x-4=0 or x+3=0

x=4 or x=-3

smaller x=  -3

larger x= +4
