If x-1 is a factor of P(x) = x - 7x²+15x –9, which of the following represents the complete factorization for P(x)?
A. (1-3)(x - 3)(x-1)
B. (x-3)(+4)(+1)
C. (x − 3)(x+3)(x-1)
D. (1-3)(x+3)(x+1)

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
