What is the first step to simplify the expression 3(x+8)^2/x+2?
a.) distribute the 3 to the terms inside the parentheses
b.) divide x by x
c.) divide 8 by 2
d.) square the binomial inside the parentheses

Option D is correct  that is square the binomial inside the parentheses.

Step-by-step explanation:

We have been given the expression:

First step we will do solve this given expression is to square the binomial inside the parenthesis so we will get:

Then distribute the  3 to the terms inside the parentheses

Therefore, option D is correct.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y
