Question

Determine the factors of x2 - 12x - 20.

Answer 1

this equation doesnt factor out so you have to use the formula x=(-b±sqrt(b2-4ac))/2a
is the number in front of x^2 = 1
b is the nuber in front of x =-12
and c is =-20

you just plug the numbers into the equation
hint (2 negative numbers multiplied together make a positive #, dont get ur signs mixed up)

Answer 2

x=(-b±sqrt(b^2-4ac))/2a
