Question

2x^4-24x^3+40x^2

Answer 1

are you trying to factor it, or solve for the roots?

Answer 2

factoring :)

Answer 3

hm, you can write it like this:

2x^2(x^2 - 12x + 20)

= 2x^2(x-10)(x-2)

Answer 4

can you please show the steps please

Answer 5

the term shared by all of 2x^4-24x^3+40x^2

is 2x^2, so factor it out

2x^2(x^2 - 12x + 20)

is what you get when you take 2x^2 out of all the terms. Now factor (x^2 - 12x + 20)

What MULTIPLIES to 20, but ADDS to -12?

10 and 2 work, but be careful your signs, -10 * -2 = 20 AND -10 + -2 adds to -12

So you get:

2x^2(x - 10)(x - 2)
