Question

x^2+17x+72=12
PLEASE HELP QUICKLY THIS IS A TEST!!!!
(Btw this is Plato)

Answer 1

Answer:

x = -5 or x = -12

Step-by-step explanation:

x^2+17x+72=12

Subtract 12 from both sides.

x^2+17x+72-12 = 12-12

x^2+17x+60=0

Then factor the left side of the equation

(x+5)(x+12) = 0

Then set the factors equal to 0

(x+5)=0 or (x+12)=0

Therefore x=-5 or -12

Answer 2

Assuming you are trying to find the values of x:

x^2+17x+72=12

             -12  -12

x^2+17x+60=0

checking factors 5, 12:

5*12=60, 5+12=17

(x+5)(x+12)=0

set both parts = to 0:

x+5=0

x=-5

x+12=0

x=-12

Answer:

x=-12, -5
