Question

simplify
2x³-4x²+3x+6+x³-5x²+6x+2

Answer 1

3 x cube minus 9 X square + 9 X + 8

Answer 2

Answer: 3x³ - 9x² + 9x + 8

Step-by-step explanation:

First of all, keep in mind that we can only add/subtract like terms only.

Like terms have same bases and same powers.

Here,

2x³-4x²+3x+6+x³-5x²+6x+2

Bring like terms together along with sign, it will be easy.

2x³ + x³ -4x² -5x² +3x +6x +6 +2

See the underlined terms, they have same bases and same powers, so we can add them now.

3x³ - 9x² + 9x + 8

Note: Adding like terms is very simple. Just add the coefficient and simply copy the base and power.

For Eg: 2 boys + 3 boys = 5 boys not 5 square boys
