Question

i. (3x – x2+ 1) + (1 + x2)

Answer 1

Answer:

3x+2

Step-by-step explanation:

this is the only answer

Answer 2

Given: The equation is$(3x -x^2+ 1) + (1 + x^2)$.

We have to solve the above expression.

As we know that adding two or more numbers together is known as an addition.

Addition as denoted by(+).

Following are the properties of addition:

1. Identity property of zero.

2. Inverse property.

3. Commutative property.

4. Associative property.

We are solving in the following way:

We have,

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

$=>3x -x^2+ 1 + 1 + x^2\\=>3x+2$

Solving the above equation further we get,

$3x+2=0\\=>3x=-2\\\\=>x=\frac{-2}{3}$

Hence, the solution of the equation is$\frac{-2}{3}$.

Note: In this problem, we are assuming that we have to solve the given equation.

Q. Solve the equation$(3x -x^2+ 1) + (1 + x^2)$.
