Answer:

y=(4x-5)(x-2)

Explanation:

y=4x^2-13x+10

There are ways you can factor 4 and that is 4 and 1 or 2 and 2. Ways to factor 10 include 10 and 1, 5 and 2.

Now, you need to find out which two sets of numbers would total up to -13x.

I usually set it up this way:
4x^2-13x+10

4 -5 (this would mean 1 * -5, which is -5)

1 -2 (this would mean 4 * -2, which is -8)

Note: Criss-cross multiply. Add the numbers up and you should get -13x.

Now write out the factored form:

y=(4x-5)(x-2)
