Both expressions are equivalent.

To prove that, let x equal a random number. For example, let x=1.
-2+3x and 3x+(-2)
-2+ (3 X 1)= 1.
(3 X 1) + (-2) =1

These two expressions are equivalent because if you had an equal sigh and equal it to the same answer like 3x+(-2)=2.

Anyways this is called the communative property. The comunuty property is when you change the statement of the equation or the expression.

Im sorry, explaining this is really weird. Trust me this is easier then it sounds. I hope this helps you.

Construct a quadratic polynomial whose zeroes are negatives of the zeroes of the

sp2606 [1]

Given:

The given quadratic polynomial is :

$x^2-x-12$

To find:

The quadratic polynomial whose zeroes are negatives of the zeroes of the given polynomial.

Solution:

We have,

$x^2-x-12$

Equate the polynomial with 0 to find the zeroes.

$x^2-x-12=0$

Splitting the middle term, we get

$x^2-4x+3x-12=0$

$x(x-4)+3(x-4)=0$

$(x+3)(x-4)=0$

$x=-3,4$

The zeroes of the given polynomial are -3 and 4.

The zeroes of a quadratic polynomial are negatives of the zeroes of the given polynomial. So, the zeroes of the required polynomial are 3 and -4.

A quadratic polynomial is defined as:

$x^2-(\text{Sum of zeroes})x+\text{Product of zeroes}$

$x^2-(3+(-4))x+(3)(-4)$

$x^2-(-1)x+(-12)$

$x^2+x-12$

Therefore, the required polynomial is $x^2+x-12$ .
