What is the coefficients of x² in (2-3x) (x²-5)​

Mathematics

Answer:

+2

Step-by-step explanation:

=> (2-3x)(x^2-5)

=> (2x^2-10-3x^3+15x)

<em>Arranging it in descending order</em>

=> -3x^2+2x^2+15x-10

<u><em>So, the coefficient of x² in this expression is +2</em></u>

This depends if you are supposed to simplify the binomials first:

If you leave it in the form provided then the coefficient would be 1

However, you can multiply the binomials together in order to simplify the expression:

(2 - 3x)( {x}^{2}  - 5)

(2  \times  {x}^{2} ) + (2 \times  - 5) + ( - 3x \times  {x}^{2} ) + ( - 3x  \times  - 5)

{ - 3x}^{3}  +  {2x}^{2}  + 15x - 10

Which then shows the coefficient would be 2

So it all depends on the directions provided, I would assume the correct answer is 2 if the directions are the exact same as provided on Brainly.

For the equation 2n - 3 = 7, what is the coefficient of the variable
scoray [572]

Answer:z

Then variable is n

Variable is an alphabet that depend on number. Then the variable there is n

And the coefficient of the variable is 2

The coefficient is the number behind a variable

And the value of the variable is

2n-3=7

Add 3 to both sides

2n-3+3=7+3

2n=10

Divide both side by 2

2n/2=10/2

n=5
