Question

How do i factor
5x^2-19x-4

Answer 1

Explanation:

An easy way is to first make a rectangle.

put 5x^2 in the bottom left

put -4 in the top right.

also, make a diamond. for the sum it will be -19x, for the product it will be -4*5x^2 which equals -20x^2

solve the diamond then put those answers in the missing squares.

hope this helps :)
