Question

Write the expression -3x 2 + 2y 2 + 5xy - 2y + 5x 2 - 3y 2 in simplest form. Then, answer the following questions using complete sentences.

How many terms are in the simplified expression?
How many of the terms in the simplified expression are negative?

Answer 1

-3x^2 + 2y^2 + 5xy - 2y + 5x^2 - 3y^2....combine like terms
2x^2 + 5xy - y^2 - 2y

u have 4 terms in the simplified expression......and 2 of them r negative.

Answer 2

= -3x² + 2y² + 5xy - 2y + 5x² - 3y²
= (5x² - 3x²) + (2y² - 3y²) + 5xy - 2y
= 2x² - y² + 5xy - 2y

In short, simplified form would be: 2x² - y² + 5xy - 2y

a) There are four terms in simplified expression.

b) Only two term is negative.

Hope this helps!
