Answer: y = (x - 1) (7x + 5)

Step-by-step explanation:

y = 7x² - 2x - 5     Use the slip and slide method.

y = x² - 2x - 35    Factor

y = (x - 7) (x + 5)  Slide 7 back in, divide -7 by 7 to get -1. Slip 7 into (x + 5).

y = (x - 1) (7x + 5)

   

  • y=7x²-2x-5
  • y=7x²-7x+5x-5
  • y=7x(x-1)+5(x-1)
  • y=(7x+5)(x-1)
