Solution
b^{2}-124b+3844
Show Solutions
Find the roots
b=62
Evaluate
\left(b-62\right)^{2}
To find the roots of the expression,set the expression equal to 0
\left(b-62\right)^{2}=0
The only way a power can be 0 is when the base equals 0
b-62=0
Move the constant to the right-hand side and change its sign
b=0+62
