Ответ:
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.
Ответ:
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
