Question

Subtracting -3x² – 1 from 2x + 1, we get
Please answer

Answer 1

Given,

Two algebraic expressions: (-3x² – 1) and (2x + 1)

To find,

The difference obtained by subtracting (-3x² – 1) from (2x + 1).

Solution,

We can simply solve this mathematical problem using the following process:

Now, according to the question;

The required difference

= (2x + 1) - (-3x² – 1)

= 2x + 1 + 3x² + 1

= 3x² + 2x + 2

Hence, the difference obtained by subtracting (-3x² – 1) from (2x + 1) is equal to (3x² + 2x + 2).

Answer 2

Answer:

Subtracting $-3x^{2}-1$ from $2x+1$, we get $3x^{2}+2x+2$

Step-by-step explanation:

Given

Two numbers $-3x^{2}-1$ and $2x+1$

We have to subtract $-3x^{2}-1$ from $2x+1$

That is,

$2x+1-( -3x^{2}-1 )$

$=2x+1+3x^{2}+1$

$=2x+3x^{2}+2$

So, the answer is $3x^{2}+2x+2$
