Question

Simplify the following expression: 4x^2 + 2 - 3x^2 + 6x - 2x

a) x^2 + 6x
b) x^2 + 4x
c) x^2 + 2x
d) 2x^2 + 4x

Answer 1

To simplify the expression, combine like terms by adding or subtracting the coefficients of terms that have the same variable and exponent. The simplified expression is x^2 + 4x + 2.

Step-by-step explanation:

To simplify the expression 4x^2 + 2 - 3x^2 + 6x - 2x, we can combine like terms by adding or subtracting the coefficients of terms that have the same variable and exponent.

So, we have (4x^2 - 3x^2) + (6x - 2x) + 2.

This simplifies to x^2 + 4x + 2.

Therefore, the correct answer is (b) x^2 + 4x.
