Question

Simplify.

(x2+4x)−(x2+6x−3)



10x−3

2x2+10x−3

−2x+3

−2x

Answer 1

Note that:

• Given expression: (x² + 4x) − (x² + 6x − 3)

Remove the brackets

• (x² + 4x) − (x² + 6x − 3)
• => x² + 4x - x² - 6x + 3

Combine like terms

• x²(1 - 1) + x(4 - 6) + 3
• => x²(0) + x(-2) + 3
• => -2x + 3
