## Which model shows the correct factorization of x2 + 2x – 8? An algebra tile configuration. 5 tiles are in the Factor 1 spot: 1 is

To factor x^2 + 2x – 8 follow these steps

1) Write to factors, with x as the first term, this way:

(x )(x )

2) The sign to the right of the x in the first factor is the same sign of the coeficient of x in the polynomial.

That is +.

The sign to the right of the x of the second factor is the product of the sign of the coefficent of x (this is +) and the sign of the independent term (this is – ).

So that is (+).(-) + -.

Now the two factors have this form:

(x + ) (x – )

3) Now find two numbers whose product is – 8 and whose difference is +2

Those numbers are + 4 and -2.

Then the two factors are:

(x + 4) (x – 2).

So the answer if that the correct factorization is (x + 4) (x – 2)

The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into both terms…c. Show the correct factorization of $8x^2 + 4x$. For example $x=2$ gives two different results, so the factorised expression is wrong. (b) Correct. (c) You can pull out another $x$ to get $$4(2x^2 + x) = 4x(2x + 1)$$ Which is the fully factorised form.
