Question

select the correct answer from the drop-down menufind the polynomial(5) is the solution set of ___A. X^2-5x + 25=0B. X^2 + 10x + 25 = 0C. X^2-10x+25=0D. X^2+5x+25=0

Answer 1

$\begin{gathered} (x+5)^2=x^2+2(x)(5)+(5)^2 \\ (x+5)^2=x^2+10x+25 \\ \\ (x-5)^2=x^2+2(x)(-5)+(-5)^2 \\ (x+5)^2=x^2-10x+25 \end{gathered}$
