Answer:
x = sqrt(7) or x = -sqrt(7) thus of the choices you have A:
Step-by-step explanation:
Solve for x:
x^2 = 7
Take the square root of both sides:
Answer: x = sqrt(7) or x = -sqrt(7)
If you mean that : this is
x=1 or x=−2 or x=−3
x3+4x2+x−6=0
Step 1: Factor left side of equation.
(x−1)(x+2)(x+3)=0
Step 2: Set factors equal to 0.
x−1=0 or x+2=0 or x+3=0
