Answer:
-5±11
Step-by-step explanation:
Our equation: 2x^2 + 5x - 12 = 0
Formula: x=-b±√b^2-4ac/2a
Formula: ax^2+bx+c=0
variable a=2 DO NOT INCLUDE x^2
variable b=5 DO NOT INCLUDE x
variable c=-12
Plug in the numbers to the formula:
x=-5±√5^2-4*2*-12/2*2
x=-5±√25+96/4
x=-5±√121/4
x=-5±11/4
-5±11 is the answer since were looking for any of the occurring numorators. Hope this helped!
