Answer:

x³+3x²+4x+12

Step-by-step explanation:

you are going to write both equations and distribute. if there are like terms, combine them and then put it order.

(x + 3) × (x² + 4)

x³ + 4x + 3x² + 12

when putting in order, you want the highest power to the left and then the lowest power to the right.

x³+3x²+4x+12

Is x-10 a factor of f(x)=5x^3+60x^2+109x+90

RUDIKE [14]

Answer:

Step-by-step explanation:

Given values are

f(x) = 5x^3+60x^2+109x+90

x = -10.

Given Polynomial is 5x^3+60x^2+109x+90 .

= (90)+(5.x^3)+(60.x^2)+(109.x)

By putting x = (-10) we can rewrite it as

= (90)+(5.(-10)^3)+(60.(-10)^2)+(109.(-10))

= (90)+(-5000)+(6000)+(-1090)

= 0

The remainder of given polynomial is 0.

Sav [38]

Answer:

see attached

Step-by-step explanation:

3x(x − 2)(5x + 2)

(x − 2)(5x + 2) expand
5x² - 8x - 4
3x ( 5x² - 8x - 4) expand
15x³ - 24x² - 12x
