2/x-2

Give the equivalent numerator if the denominator is (x-2)(x-1)(x-6).
2x² - 10x + 12
2x² - 14x + 12
2x² - 14x - 10

Step-by-step explanation:

Numerator = 2*(x-1)(x-6)

(x-1)(x-6)= x*(x-6) -1*(x-6)

            =x*x - x*6 - 1*x - (-1)*6

           = x² - 6x - x + 6

           = x² -7x + 6

Numerator = 2*(x-1)(x-6) = 2* (x² -7x + 6) = 2x² - 14x + 12

step-by-step explanation:

equation

you are asked to write the equation

  expression = 0

using the given expression. when you do that, you have

  2x^2-2x-12 = 0

factoring

you can see that each of the coefficients is even, so a factor of 2 can be removed immediately.

  2(x^2 -x -6) = 0

if you multiply the binomials (x+a)(x+b), you get

  (x +a)(x +b) = x^2 +(a+b)x +ab

this tells you the coefficient of x is the sum of two factors of the constant term. here, that means -1 is the sum of two factors of -6. we want to know those factors so we can factor the trinomial.

  -6 = -1×6 = -2×3 = -3×2 = -6×1

the factor pair that sums to -1 is {-3, 2}, so our factorization is

  2(x -3)(x +2) = 0

solutions

the solutions to this equation are the values of x that make the product zero. a product is zero only when only of the factors of the product is zero. here, that means

  x - 3 = 0

  x = 3 . . . add 3 to both sides of the equation

or

  x +2 = 0

  x = -2 . . . add -2 to both sides of the equation

the solutions to the equation are x=3 or x=-2. both of these values of x satisfy the equation—they make it be true.

i got 10.28 but that rounds up to 10.3
