Factor. 24x^3 + 20x^2

Question

Can someone please help with this one?

Thank you

 

Answer 1

24x³ + 20x²

 

4x² (6x + 5) = 0

 

(4x²) = 0 or (6x + 5) = 0

 

x² =  0/4

x² = 0

x = 0

 

or

 

 

6x = -5

x = -5/6

Answer 2

Factor: 24x^3 + 20x^2

 

24x^3 + 20x^2

 

2*2*2*3*x*x*x + 2*2*5*x*x

 

Greatest Common Factor is 2*2*x*x:

 

2*2*x*x(2*3*x + 5)

 

4x^2(6x + 5) is factored form of 24x^3 + 20x^2.

Answer 3

Hi Adeline;

24x^3 + 20x^2

4x²(6x+5)

If you set this equal to zero, then the 4x² and/or (6x+5) is equal to zero.

0=4x²..........6x+5=0

0=x..............6x=-5

....................x=-5/6
