    first multiply (x + 5)(x + 5) can you do this?

    I put (x+5)(x+5) on my calculator and it gave 225

    So I don't need to put on my calculator (x+5)*(x+5)?

    no this is algebra and you use whats known as the Distributive Law first multiply the second parenthesis by x then by +5: (x + 5)(x + 5) = x(x + 5) + 5(x + 5) = x*x + x*5 + 5*x + 5*5 = x^2 + 10x + 25 are you familiar with algebra?

    yes then second step is (x + 5)(x^2 + 10x + 25) = x(x^2 + 10x + 25) + 5(x^2 + 10x + 25)
