Question

Subtract the sum
(-3+ 5x - 3x²)and (6x² + 8x -9)
from 10 .​

Answer 1

Given:

Two expressions:

• (-3 + 5x - 3x²)
• (6x² + 8x - 9)

A number:

• 10

What To Do:

First we have to find the sum of the two expressions and subtracted the sum from 10.

Solution:

• Finding the sum

(-3 + 5x - 3x²) + (6x² + 8x - 9)

Remove the brackets,

⇒ -3 + 5x - 3x² + 6x² + 8x - 9

Rearrange the like terms,

⇒ - 3x² + 6x² + 5x + 8x - 3 - 9

Solve the like terms,

⇒ 3x² + 13x - 12

• Finding the difference

10 - (3x² + 13x - 12)

Remove the brackets,

⇒ 10 - 3x² - 13x + 12

Rearrange the like terms,

⇒ -3x² - 13x + 12 + 10

Solve the like terms,

⇒ -3x² - 13x + 22

∴ So, the difference is -3x² - 13x + 22.
