QUIZ 1 – ILLUSTRATIONS OF QUADRATIC EQUATIONS Identify if the following equations are QUADRATIC or NOT QUADRATIC. Answer QE if the equation is QUADRATIC and NQE if NOT QUADRATIC. 3m + 8 = 15 x2 -5x + 10 = 0 12 – 4x = 0 2t2 – 7t = 12 6 – 2x + 3x2 = 0 25 – r2 = 4r 3x (x – 2) = -7 12 h-6=0 (x + 2)2 = 0 (w – 8) (w + 5) = 0 Identify if the following quadratic equations are written in standard form or not. Answer SF if it is in standard form and NSF if not in standard form. -2x2 + 3x - 7 = 0 -2x2 + 6x - 5 = 0 x2 + 7x + 12 = 0 2x2 + 5x - 7 = 0 2x2 - 6x - 15= 0 x2 – 49 = -3x x2 – 8x + 16 + 8 = 0 x2 + 4x + 4 = 3x + 6 3x2 – 6x = 0 x2 – 9 = 0
