Answer:

[tex]5(x-3)(x-4)[/tex]

Step-by-step explanation:

[tex]5x^2-35x+60[/tex]

Start by factoring out a 5:

[tex]5(x^2-7x+12)[/tex]

We need to find two integers that have a product of 12, and a sum of -7:

(-3)(-4)=12

-3-4=-7

We can split -7x into -3x and -4x

[tex]5(x^2-3x-4x+12)[/tex]

Factor each half separately:

[tex]5[x(x-3)-4(x-3)][/tex]

Since x and -4 are both being multiplied by x-3, we can combine them:

[tex]5(x-3)(x-4)[/tex]
