Question

Which comparison of the two equations is accurate?

Equation A: x2+3x-6 = x+2
Equation B: x2+3x-6 = 3 x+2

Answer 1

A: x2+3x-6=x+2

Explanation:

A: x2+3x-6=x+2

x2+3x-x-6-2=0

x2+2x-8=0

(x+4)(x-2)=0

x=-4, x=2

B:x2+3x-6=3x+2

x2+3x-3x-6-2=0

x2-8=0

x2=8

x=±
`√(8\\)` Not accurate

Answer 2

Equation B: 2x+3x-6 is accurate
