Question

Solve by factoring.
4n^2 - 33n -5 = 0

Answer 1

im stuck on this :L

Answer 2

notice how a = 4, b = -33 and c = -5

use the discriminant formula D = b^2 - 4ac to get


D = b^2 - 4ac
D = (-33)^2-4(4)(-5)
D = 1169

Now take the square root of 1169 to get sqrt(1169) = 34.1906419945576

The square root result is NOT a whole number. So the discriminant isn't a perfect square

when the discriminant isn't a perfect square, this means that we cannot factor

ohhh okay thanks!
