Question

Simplify. −5x4(−3x2+4x−2)

Answer 1

Answer:

$15x^{6}-20x^{5}+10x^4)$

Step-by-step explanation:

We have been given an expression $-5x^4(-3x^2+4x-2)$ and we are asked to simplify our given expression.

We will use distributive property $a(b+c)=a*b+a*c$ to simplify our given expression.

Upon distributing $-5x^4$ we will get,

$(-5x^4*-3x^2)+(-5x^4*4x)-(-5x^4*2)$

Using exponent property $a^b*a^c=a^{b+c}$ we will get,

$(15x^{4+2})+(-20x^{4+1})-(-10x^4)$

$(15x^{6})+(-20x^{5})-(-10x^4)$

$15x^{6}-20x^{5}+10x^4)$

Therefore, our given expression simplifies to $15x^{6}-20x^{5}+10x^4)$.
