Question

Find (y + 3)(y2 + 8y – 2). (y + 3)(y2 + 8y – 2) =

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

(y + 3)(y² + 8y – 2). (y + 3)(y² + 8y – 2)

simplify

Step 02:

We must apply the algebraic rules to find the solution.

(y + 3)(y² + 8y – 2). (y + 3)(y² + 8y – 2)

Part 1:

(y + 3)(y² + 8y – 2) = y³ + 8y² - 2y + 3y² + 24y - 6

= y³ + 11y² + 22y - 6

Part 2:

(y³ + 11y² + 22y - 6) * (y³ + 11y² + 22y - 6) =

`y^6+11y^5+22y^4-6y^3+11y^5+121y^4+242y^3-66y^2+22y^4+242y^3+484y^2-132y-6y^3-66y^2-132y+36`
`y^6+22y^5+165y^4+472y^3+352y^2-264y\text{ }+36`

That is the full solution.
