Question

Use the zero product property to find the solutions to the equation (x + 2) (x + 3) = 12.

Answer 1

Answer:

Solution

x=1

x=−6

Step-by-step explanation:

x(+3)+2(x+3)=12

Answer 2

Answer: Sol={-6,1}

Step-by-step explanation:

1) we are searching value of x in R

$(x+2)(x+3)=12\\x^2+2x+3x+6-12=0\\x^2+5x-6=0\\\\x^2-x+6x-6=0\\\\x(x-1)+6(x-1)=0\\\\(x-1)(x+6)=0\\\\x=1\ or\ x=-6\\Sol=\{-6,1\}$

2) we are searching value of x in Z.

12=1*12 =(-1)*(-12)

12=2*6=(-2)*(-6)

12=3*4=(-3)*(-4)
