Question

What would be the most logical first step for solving this quadratic equation?

x²+2x-11=4
A. Add 11 to both sides
B. Take the square root of both sides
C. Divide both sides by x
D. Subtract 4 from both sides

Answer 1

D. Subtract 4 from both sides

Explanation:

When you're solving a quadratic equation you want to use the quadratic formula
`\frac{-b+ \sqrt[]{b^(2) -4ac } }{2a}`.
To get the quadratic equation into this form, you first need to convert it into
`ax^(2) +bx+c=0` which means the first step would be to subtract 4 on both sides.
