WhaThe factorization of x2 + 3x – 4 is modeled with algebra tiles.t is the factored form of x2 – x – 2?
Nataly [62]

Answer:

  x^2 -x -2 = (x -2)(x +1)

Step-by-step explanation:

To factor x^2 -x -2, you look for factors of -2 that have a sum of -1:

  -2 = (-1)(2) = (1)(-2) . . . . . the latter pair has a sum of -1

Then these are the constants in the binomial factors:

  x^2 -x -2 = (x +1)(x -2)

_____

<em>Comment on the question</em>

The fact that x^2 +3x -4 is modeled with algebra tiles seems to be irrelevant to the question that is actually asked.

3. (x2 + 17x + 63) ÷ (x + 8) =
Stolb23 [73]

3(2x + 17x + 63) \div (8 + x) \\ 6x + 51 + 189 \div 8x
6x \times 8x = 48x
51 + 189 \div 48x \\ 240 \div 48x \\ 5x
= 5x
