Factor the following expression. 18x^2-60x+50

Question:

Factor the following expression: 18x^2 - 60x + 50

Steps:

So, what do they all have in common?

What is the factor of 18, 60, and 50 ?

Since you cant make an odd number like 5 go into 18 you can use 2 as the factor. So...,

1. 2(9x^2 - 30x + 25)

If you get stuck with #1 just check to make sure , so you use the distributive property formula to check:

a(b + c) = ab + ac

2. Next, break down 9x^2 - 30x + 25:

So what can you factor out to make 9x^2 and 25?

3 and 5

So.. put it in the equation:

(3x - 5)(3x - 5)

and make sure you have a minus sign and if you get stuck just check the

= 9x^2 - 15x - 15x + 25

= 9x^2 - 30x + 25

so that was a correct answer!

Now put the 2 and the (3x - 5)(3x - 5) back into the equation to get your final

2(3x - 5)^2 which is the answer!

Hope that helped!!
