Find all possible solutions for the following equation
x²+7x+63=63
2 answers:
Answer:
Step-by-step explanation:
X^2+7x+63=63
<=> x^2+7x=63-63=0
<=> X(x+7)=0
<=> x1=0
X2=-7
Answer:
0 or -7
Step-by-step explanation:
x² + 7x + 63 = 63
⇔ x² + 7x + 63 - 63 = 0
⇔ x² + 7x = 0
⇔ x(x + 7) = 0
So either: x = 0
or x + 7 = 0 ⇔ x = -7
