Help please!! FACTOR IT

1. Subtract 18 from both sides to get the equation set to 0:

x2 + 7x - 18 = 0

Now factor. Given the negative sign in front of the 18, you will have (x + ) (x - ) as your factors, with the larger one being positive. Now, which factors of 18 can be combined to get a result of 7? I'll leave that for you.

2- 2.3 Solve : p-7 = 0

Add 7 to both sides of the equation :

p = 7

3-Final result :

(m - 1) • (m - 8)

Trying to factor by splitting the middle term

1.1 Factoring x2-16x+63

The first term is, x2 its coefficient is 1 .

The middle term is, -16x its coefficient is -16 .

The last term, "the constant", is +63

Step-1 : Multiply the coefficient of the first term by the constant 1 • 63 = 63

Step-2 : Find two factors of 63 whose sum equals the coefficient of the middle term, which is -16 .

-63 + -1 = -64

-21 + -3 = -24

-9 + -7 = -16 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -9 and -7

x2 - 9x - 7x - 63
