Simplify the algebraic expressions by removing grouping symbols.x2 �

1.	Simplify the algebraic expressions by removing grouping symbols.x2 – [3x + [2x – (x2 – 1)] + 2]
Answer» Given x²– [3x + [2x – (x²– 1)] + 2] First we have to remove the parentheses, then remove braces, and then the square brackets. Then we get, = x² – [3x + [2x – (x² – 1)] + 2] = x² – [3x + [2x – x² + 1] + 2] = x² – [3x + 2x – x² + 1 + 2] = x² – [5x – x² + 3] On simplifying we get = x² – 5x + x² – 3 = 2x² – 5x – 3

Given x²– [3x + [2x – (x²– 1)] + 2]

First we have to remove the parentheses, then remove braces, and then the square brackets.

Then we get,

= x² – [3x + [2x – (x² – 1)] + 2]

= x² – [3x + [2x – x² + 1] + 2]

= x² – [3x + 2x – x² + 1 + 2]

= x² – [5x – x² + 3]

On simplifying we get

= x² – 5x + x² – 3

= 2x² – 5x – 3
