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

Answer:

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

Step-by-step 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

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