Question

How do you factor: #y= x^2 + 6x – 27 #?

Answer 1

To factor trinomials of the form y = `ax^2` + bx + c, a = 1, find two numbers that multiply to c and that add to b.

Explanation:

Two numbers that multiply to -27 and add to +6 are +9 and -3.

So, y = #x^2 + 6x - 27
y = (x + 9)(x - 3)

Hopefully this helps!
