Question

What is The Answer of this ? I need your help guys . 2 ( x²+2)-1

Answer 1

Given expression is $2(x^2+2)-1$

There is no specific direction for this problem so that means we have to simplify it if possible.

To simplify any expression we always use PEMDAS

P means Parenthesis so we will start from the parenthesis part $(x^2+2)$

Since there is no value of x given or there are no like terms to combine so parenthesis part will remain as it is.

E means exponent but there is no known exponent term available for simplification.

M means multiplication so we will multiply 2 to the parenthesis part.

We get:

$=2x^2+2*4-1$

$=2x^2+8-1$

D means division.

A means addition

S means subtraction.

Since there is no more term which can be divided, addded or subtracted so the final answer is $2x^2+8-1$
