a C Directions/Instructions I. Determine if the given equation is quadratic or not. If yes, write its standard form and identify the values of a, b, and c. (1 point for each correct answer per box) Quadratic Standard Form Equation b YES/NO ax2 + bx + c = 0 Example: 5x + 8 = 0 NO Example: 2x2 + 3 = 4x YES 2x2 - 4x + 3 = 0 2 -4 3 1.) x +3= 9 2.) 4x2 + 3x -9= 0 YES 3.) x2 - 5x = -6 - 4.) x(x + 4) = x2 – 12 5.) (2x + 5)(x - 2) = -10 6.) (x2 + 4)(x2 + 3) = 25 7.) (x - 1)(x+2) = x (x + 5) 8.) (x - 3)2(x + 1) = x(x + 2) 9.) (x – 4)2 = 16 - 8x 10.) 5x2 – 3x = 2x2 - 15 - - - - -
