Use the zero property to find the solutions to the equation X2 + X - 30 = 12

Answer: 6 or-7

Step-by-step explanation:

X2+x-30=12

Collect like terms

X2+x-30-12=0

X2+x-42=0

Factorise

Factors of - 42 that will give + x is + 7&-6

Substitute

X2+7x-6x-42=0

X (x+7) - 6 (x+7) = 0

(X-6) (x+7) = 0

X-6=0

X=6 or

X+7=0

X = - 7

Therefore x=6 or - 7

X=6, X=-7

Step-by-step explanation:

X^2+X-30=12

X^2+X-30-12=12-12-Subtract 12 from both sides

a=1 b=1 c=-30 - then place into the quadratic formula and you will get the answers.
