    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
