Use the quadratic formula to solve the equation.x2 + 10x + 24 = 0
A. {- 6, - 4} B. {6, - 4} C. {24, 0} D. {6, 4}
If necessary, write the equation in the standard form ax2 + bx + c = 0. Then identify the values of a, b, and c. Do not actually solve the equation.-6x2 + 8x = 2
A. a = -6, b = -2, c = 8 B. a = -6, b = 8, c = 2 C. a = -6, b = 2, c = 8 D. a = -6, b = 8, c = -2
Use matrices to solve the system of equations. If the system has no solution, so indicate.
A. ( 6, 0, 2 ) B. ( 6, 0, 5 ) C. ( 6, 2, 2 ) D. ( 5, 2, 2 ) E. No solution.
Factor completely. If the polynomial cannot be factored, write "prime."9x4 - 24x3 + 16x2
A. x2(9x - 1)(x - 16) B. (9x2 + 4)(x2 + 4) C. x2(3x - 4)(3x - 4) D. x(3x + 4)(3x + 4)
