What is the sum of the given polynomials in standard form? (x2 – 3x) (–2x2 5x – 3) –3x2 8x – 3 –x2 – 2x – 3 3x2 – 8x 3 –x2 2x – 3

Option (d) is correct.

Step-by-step explanation:

Given : Polynomials

We have to find the sum of given polynomials.

Consider the given polynomials  

Sum is given by

Expand by removing brackets , we have

Apply plus minus sign , we get,

Adding like terms,

LIKE TERMS are terms having same variable with same degree, we get,

Thus, Option (d) is correct.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
