Given :

The expressions - 2x² + x + 1 and x² + 2x - 3

To find :

How much - 2x² + x + 1 is less than x² + 2x - 3

Solution :

Step 1 of 2 :

Write down the given expressions

The expressions are - 2x² + x + 1 and x² + 2x - 3

Step 2 of 2 :

Find the required expression

Let - 2x² + x + 1 is P less than x² + 2x - 3

By the given condition

- 2x² + x + 1 + P = x² + 2x - 3

⇒ P = ( x² + 2x - 3 ) - ( - 2x² + x + 1 )

⇒ P = x² + 2x - 3 + 2x² - x - 1

⇒ P = 3x² + x - 4

Hence - 2x² + x + 1 is 3x² + x - 4 less than x² + 2x - 3
