Select the two values of x that are roots of this equation. x2 + 2x- 6 = 0
A. x= -1 - 7
B. x= -1+ 7
C. x = -1 - 2-17
D. x= -1+2-17

A. x= -1 - 7

B. x= -1+ 7

Step-by-step explanation: or this equation: a=1, b=2, c=-6

1x2+2x+−6=0

Step 1: Use quadratic formula with a=1, b=2, c=-6.

x=−b±√b2−4ac/2a

x=−(2)±√(2)2−4(1)(−6)/2(1)

x=−2±√28/2

x=−1+√7 or x=−1−√7
