Question

Which expression is equivalent to (x^2-3x)(4x^2+2x-9)?

Answer 1

Answer:

Below is your answer hope it helps

Step-by-step explanation:

x^2(4x^2+2x-9)-3x(4x^2+2x-9)

=4x^4+2x^3-9x^2-12x^3-6x^2+27x

=4x^4-10x^3-15x^2+27x

Answer 2

Answer:

$\Huge \boxed{4x^4-10x^3-15x^2+27x}$

Step-by-step explanation:

$\medium \textnormal{To solve this problem, first, you have to isolate it by the x on the expression of equivalent.}$

$\medium \textnormal{Solve with parenthesis.}$

$\displaystyle x^2*4x^2+x^2*2x+x^2(-9)+(-3x)*4x^2+(-3x)*2x+(-3x)(-9)$

$\large \textnormal{ Apply by the minus into the plus sign.}$

$\displaystyle 4x^2x^2+2x^2x-9x^2-3*4x^2x-3*2xx+3*9x$

$\large \textnormal{Solve.}$

$\displaystyle 4x^2x^2+2x^2x-9x^2-3*4x^2x-3*2xx+3*9x=\boxed{4x^4-10x^3-15x^2+27x}$

$\large \textnormal{In conclusion, the correct answer is \boxed{4x^4-10x^3-15x^2+27x}.}$
