Question

(2x2 − 5x)(4x2 − 12x + 10)

multiply

Answer 1

is this 2x to the power of 2?
if it is then this is easy
list it out (just to show you how its solved)
2x^2*4x^2
2x^2*(-12x)
2x^2*10
then list the other one
-5x*4x2
-5x*(-12x)
-5x*10
so the whole answer is
8x^4+(-24x^3)+(-20x^3)+20x^2+60x^2+(-50x)

Answer 2

`8x^4-44x^3+80x^2 -50x`

Explanation:

`(2x^2 - 5x)(4x^2 - 12x + 10)`

To multiply two parenthesis , first we multiply 2x^2 with second parenthesis

`(2x^2)(4x^2 - 12x + 10)=8x^4-24x^3+20x^2`

Now we multiply -5x inside the second parenthesis

`(-5x)(4x^2 - 12x + 10)= -20x^3+60x^2-50x`

We add both the answers we got

`8x^4-24x^3+20x^2 -20x^3+60x^2-50x`

Combine like terms and simplify it

`8x^4-44x^3+80x^2 -50x`
