Step-by-step explanation:
Squaring a number means you're multiplying the number by itself. This would mean (6b)^2 = (6b)(6b).
Answer:
Yes
Step-by-step explanation:
X2+10x+25=0
So let's solve
10=5,5
25=5,5
So let's continue
X2+5x+5x+25
Let's factorise
X(x+5)+5(x+5)=0
(X+5)(x+5)=0
So
X+5=0
Substrate 5 from both sides
X=-5(twice)
So the answer is yes
