16? using 16, you have (3x2 + 4)(3x2 + 4) = 9x2 + 24x + 16
Answer this question…A. x4 + 2x3 + 9x2 + 4 B. x4 + 4x3 + 9x2 + 4 C. x4 + 2x3 + 9x2 + 4x + 4 D. x4 + 2x3 + 9x2 - 4x + 4
= 53 9x3 + 9x2 + 5x1+ 3x1 27 + 18 + 5 + 3
The discriminant of a quadratic ax2 + bx + c is b2 - 4ac; thus: the discriminant of -9x2 + 6x + 14 is 62 - 4 x -9 x 14 = 540
