THIS USER ASKED 👇
Which shows one way to determine the factors of x3 – 9×2 + 5x – 45 by grouping? x2(x – 9) – 5(x – 9) x2(x + 9) – 5(x + 9) x(x2 + 5) – 9(x2 + 5) x(x2 – 5) – 9(x2 – 5)
THIS IS THE BEST ANSWER 👇
X³ – 9x² + 5x – 45
x² (x – 9) – 5 (x – 9) ⇒ x³ – 9x² – 5x + 45 INPUT
x² (x + 9) – 5 (x + 9) ⇒ x³ + 9x² – 5x – 45 INPUT
x (x² + 5) – 9 (x² + 5) ⇒ x³ + 5x – 9x² – 45 RIGHT
It just needs to be reorganized.
x (x² – 5) – 9 (x² – 5) ⇒ x³ – 5x – 9x² + 45 IONCHUR
