Answer 2

Given,

2x² (x + 2) – 3x (x² – 3) – 5x(x + 5)

To find,

Simplify

Solution,

⇒   2x² (x + 2) – 3x (x² – 3) – 5x(x + 5)

⇒   2x²(x) + 2x²(2) - (3x)(x²) -3x(-3) -5x(x) - 5x(5)

⇒   2x³+4x²-3x³+9x-5x²-25x.

Now, add the like terms after comparing all the terms and grouping them together.

⇒   (2x³-3x³)+(4x²-5x²)+(9x-25x).

⇒   -x³-x²-16x

Hence, the simplification of 2x² (x + 2) – 3x (x² – 3) – 5x(x + 5) is-

 -x³-x²-16x
