Question

Solve for x in the equation x2+10x+12=36

Answer 1

x=2

Explanation:

so

x2+10x+12=36

x2+10x=24

12x=24

x=2

CHECK:

2(2)+10(2)+12

4+20+12

20+16

36=36

Answer 2

x² + 10x + 12 = 36

x² +10x + 12-36 = 0

x² + 10x - 24 = 0

now by factorization;

x² + 12x - 2x - 24 = 0

x(x+12) -2(x+12) = 0

(x+12)(x-2) = 0

Now, x+12 = 0 and x-2 = 0

x = -12 and x = 2

x= -12, 2

Thus the values for x is -12 and 2.
