Answer:
x=2 and x=-4
Step-by-step explanation:
x²+2x-8
Formula for finding roots of a quadratic equation is ax² + bx + c = 0
x=-b±√b²-4ac/2a
a=1,b=2,c=-8
x=-2±√2²-4(1)(-8)/2(1)
x=-2±√4+32/2
x=-2±√36/2
x=-2±6/2
when x=+6
x=-2+6/2
x=4/2
x=2
when x=-6
x=-2-6/2
x=-8/2
x=-4
therefore the solutions are x=2 and x=-4
