Assume that the expression under the radical represents a non-negative real number. The expression is (x squared + 20x + 100) under the radical. If you could just simply explain the steps for solving this problem, I will be forever grateful to you. Thanks in advance.

    There is no much steps, the idea is to simplify the expression.

    For this expression (X^2+20X+100) will be simplified (X+10)^2

    So (X+10)^2 under radical result in (X+10)

    That is all

    SQRT(x^2 + 20x + 100) = SQRT[(x + 10)^2] = x + 10

    sqrt(x^2+20x+100) = sqrt(x+10)sqrt(x+10) = x+10

    Hi,

    Factor the expression inside the radical.

    . _____________

    √x² + 20x + 100 =

    . ________

    √(x + 10)². = x + 10 <==ANSWER

    I hope that helps!! :-)
