Question

2x^2(-5x^2-4)+4x^4 in simplist form, plz help

Answer 1

Answer:

-6x^4-8x^2 or -2x^2(3x^2+4)

Step-by-step explanation:

Given expression is:

$2x^2(-5x^2-4)+4x^4$

In order to write the expression in simplest form we have to multiply the terms which needs to be multiplied.

So,

$= -10x^4-8x^2+4x^4$

Combining alike terms

$= -10x^4+4x^4-8x^2\\=-6x^4-8x^2$

Can also be written as:

$= -2x^2(3x^2+4)$

Answer 2

Answer:

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

Step-by-step explanation:

2x^2(-5x^2 - 4) + 4x^4

Distribute the 2x^2 over the parentheses:

= -10x^4 - 8x^2 + 4x^4

= - 6x^4 - 8x^2

=  -2x^2(3x^2 + 4).
