Question

subtract the sum of 3 x square - 5 x and minus x square + 2 X + 3 from the sum of 2 + 3 X and 7 - 2 X + 2 x square​

Answer 1

Answer:

if I've understood what u asked correctly,

then the answer should be 2x + 4

Answer 2

Given:

Four expressions:

• 1st expression: 3x² - 5x
• 2nd expression: -x² + 2x + 3
• 3rd expression: 2 + 3x
• 4th expression: 7 - 2x + 2x²

What To Do:

We have to

• Find the sum of 1st and 2nd
• Find the sum of 3rd and 4th
• Then subtract the sum of 1st and 2nd from the sum of 3rd and 4th.

Solution:

• Finding the sum of 1st and 2nd expression.

(3x² - 5x) + (-x² + 2x + 3)

Remove the brackets,

⇒ 3x² - 5x - x² + 2x + 3

Rearrange the like terms,

⇒ 3x² - x² - 5x + 2x + 3

Solve the like terms,

⇒ 2x² - 3x + 3

• Finding the sum of 3rd and 4th expression.

(2 + 3x) + (7 - 2x + 2x²)

Remove the brackets,

⇒ 2 + 3x + 7 - 2x + 2x²

Rearrange the like terms,

⇒ 2x² + 3x - 2x + 2 + 7

Solve the like terms,

⇒ 2x² + x + 9

• Finding the difference

(2x² + x + 9) - (2x² - 3x + 3)

Remove the brackets,

⇒ 2x² + x + 9 - 2x² + 3x - 3

Rearrange the like terms,

⇒ 2x² - 2x² + x + 3x + 9 - 3

Solve the like terms,

⇒ 4x + 6

∴ So, the difference is 4x + 6.
