# Squares and Square Roots: The Life Quadratic True or False

 1 Which of the following is not a quadratic equation? -> x2 = -1 True False 2 If the polynomial 4x2 + 9x + c is the square of binomial of degree 1, what is c? -> True False 3 The polynomial x2 + 11x + c is the square of which binomial? -> True False 4 How many solutions are there to the equation x2 + 12x = -36? -> more than I care to think about True False 5 How many solutions are there to the equation x2 – 4x = 17? -> two True False 6 Solve: x2 + 14x + 40 = -5. -> x = -3, x = -11 True False 7 Solve, assuming that a, b, c are constants and c is not zero: cx2 + ax + b = 0. -> True False 8 Solve: 2x2 + 5x + 3 = 7. -> True False 9 If the quadratic equation ax2 + bx + c = 0 has discriminant 0, how many solutions does the equation have? -> oh so many True False 10 A student was asked to solve the equation 3x2 + 10x – 11 = 0. They wrote down the following work.    Where, if anywhere, did the student make their first mistake? -> In line 1. True False
