Question

I need help on algebra

Answer 1

Just remember the syllables PEMDAS which stand for Parentheses, Exponents, Multiplication, Division, Addition and Subtraction. If you can’t remember it, just write it on the side of your paper. But make sure to use it in that order.

Answer 2

Answer:

1)   5x³ + 3x²

2)  25 - 3x⁵

3)  -4ab + 2a² + 26

4)   p²q³ + pq

Step-by-step explanation:

Like terms are expressions like 3x and 2x or 5x² and 8x².

1)  x² + 5x³ + 2x²

    5x³ + 3x²

2)  -2x⁴ + 16 + 2x⁴ + 9 - 3x⁵

     -2x⁴ + 2x⁴ + 25 - 3x⁵

      25 - 3x⁵

3)  ab - a² + 4² - 5ab + 3a² + 10

     ab - a² + 16 - 5ab + 3a² + 10

     ab - a² - 5ab + 3a² + 26

     ab - 5ab + 2a² + 26

     -4ab + 2a² + 26

4)  3p²q² - 3p²q³ + 4p²q³ - 3p²q² + pq

     3p²q² + p²q³ - 3p²q² + pq

     p²q³ + pq
