Adding a rational number with an irrational number results in __________________
What is an irrational number?
A polynomial with 2 terms
What is a binomial?
What is the mistake?
x² + 2x - 4x² + 3x = -3x² + 5x²
Do not add the exponents should be -3x² + 5x
(5x² - 6x +2) + (x² + 3x - 3)
6x² -3x - 1
(2x - 4) (3x - 3)
