    (x+a) * (x+b)

    First off you have to solve whats in the parentheses

    First Parentheses: x*x = x^2 Then : x*b = bx

    I multiplied x times x which is x squared, then i multiplied x times b which equals bx

    Second parentheses: a*x = ax, Then: a*b=ab

    i multiplied a times x which is ax, then i multiplied a times b and that equals ab

    so our answer is = x2+bx+ax+ab

    Right here

    All of this together
