Question

From the sum of 4x²+5y+3 and 3y+x²+2 subtract 6x²-8 gives __________________​

Answer 1

Answer:

8y - x² + 13

Step-by-step explanation:

4x² + 5y + 3 +(3y + x² + 2)

= 4x² + 5y + 3 + 3y + x² + 2

= 4x² + x² + 5y + 3y + 3 + 2

= 5x² + 8y + 5

5x² + 8y + 5 - (6x² - 8)

= 5x² + 8y + 5 - 6x² + 8

= 5x² - 6x² + 8y + 5 + 8

= -x² + 8y + 13

= 8y - x² + 13
