### Examples on Solving Math Expressions

Given below are some examples on solving math expressions.

**Example 1:**Simplify $4x^{2} + 7 + x^{2} + 5 + x$

Solution:Group the terms carrying the same variable

$4x^{2} + 7 + x^{2} + 5 + x = (4x^{2} + x^{2}) + x + (7 + 5)$

$= (5x^{2}) + x + (12)$

$= 5x^{2} + x + 12$

Answer: $5x^{2} + x + 12$

**Example 2:**Simplify $3(4x^{2} + 7x - 2) + 4(6x + 2) - 6x^{2}$

Solution:Rewrite the expression by using the Distributive Property.

$3(4x^{2} + 7x - 2) + 4(6x + 2) - 6x^{2} = 3(4x^{2}) + 3(7x) - 3(2) + 4(6x) + 4(2) - 6x^{2}$

$= 12x^{2} + 21x - 6 + 24x + 8 - 6x^{2}$

$= (12x^{2} - 6x^{2}) + (21x + 24x) + (8 - 6)$

$= 6x^{2} + 45x + 2$

Answer: $6x^{2} + 45x + 2$
