Question

Find the real zeroes
y = 4x^3 -20x^2+25x

Answer 1

Set right side = 0
Then start by factoring x from the trinomial.
Then either factor the quadratic trinomial or use the quadratic formula.

Answer 2

ok i got x( 4x^2 -20x + 25)

Answer 3

x( 4x^2 -20x + 25) = 0
Good.
Now either try to factor the trinomial or use the quadratic formula.

Answer 4

thanks, my stupid sister wont use this program

Answer 5

im trying to show her

Answer 6

Do you know how to factor the trinomial, or do you need help?

Answer 7

use the quadratic formula?

Answer 8

That'll do it.
