Answer: (x-8)(x+6)

Step-by-step explanation: For this equation, you need to figure out what two numbers add up to add -2, and multiply to get -48.

These numbers are +6 and -8. So the factored pair will be (x+6)(x-8)

Hope this helps:)

Answer: d

Step-by-step explanation:

This a trinomial so to find the factorization you need just to solve this equation :

  • x²-2x-48=0
  1. a=1
  2. b=-2
  3. c=-48
  • Δ=(-2)²-4*1*(-48)=196
  • so our trinomial has 2 solutions :
  • [tex]\left \{ {{y=\frac{2+\sqrt{196} }{2} } \atop {x=\frac{2-\sqrt{196} }{2} }} \right.[/tex]

x=8 and y=-6

the factorisation is  f(x)=a* (x-8)(x-(-6))

       the answer is : (x+6) (x-8)
