−4x²−53

Step-by-step explanation:

Let's simplify step-by-step.

−4x²−8−45

= −4x² + −8 + −45

Combine Like Terms:

=−4x²+−8+−45

=(−4x²)+(−8+−45)

=−4x²+−53

- 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

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.
