PLEASE HELP Part 1: Solve each of the quadratic equations below and describe what the solution(s) represent to the graph of each. Show your work to receive full credit. 0 = x2 + 5x + 6 0 = x2 + 4x + 4 Part 2: Using complete sentences, answer the following questions about the two quadratic equations above. Do the two quadratic equations have anything in common? If so, what? What makes y = x2 + 4x + 4 different from y = x2 + 5x + 6?

    X^2 + 5x + 6 = 0 this can be factorised as X^2 + 2x + 3x + 6 = 0 X(x+2) + 3 ( x + 2) = 0 (x+2) * ( x + 3 ) = 0 x = -2 or -3 For x^2 + 4x + 4, it is factorised as x^2 + 2x + 2x + 4 =0 this simplifies to (x+ 2) * (x+2) =0 or (x+2)^2 =0 in both cases, x = -2

    Quadratic formula makes sense when you cannot find the factors but it is too lengthy for small questions like this
