Resolve the quadratic trinomials into factors:11x2 – 54x + 63 |
|
Answer» We have, 11x2 – 54x + 63 The coefficient of x2 is 11 The coefficient of x is -54 Constant term is 63 So, we express the middle term -54x as -33x – 21x 11x2 – 54x + 63 = 11x2 – 33x – 21x – 6 = 11x (x – 3) – 21 (x – 3) = (11x – 21) (x – 3) |
