Answer 1

Answer:

1)  $(-y^2-4y-8+4y^2+6y-3)$

2)  $32x^5y^4z^2$

3)  $x^3-9x^2+14x+24$

Step-by-step explanation:

Given the expression we have to simplify the expression

1)   $(-y^2-4y-8)-(-4y^2-6y+3)$

⇒ $(-y^2-4y-8+4y^2+6y-3)$

Combining like terms, we get

⇒ $3y^2+2y-11$

2.)    $(2x^2y^3z^2)(4xy.4x^2)$

⇒ $(2x^2y^3z^2)(16x^3y)$

⇒ $32x^5y^4z^2$

3.)   $(x-4)(x^2-5x-6)$

⇒ $x^3-5x^2-6x-4x^2+20x+24$

⇒ $x^3-9x^2+14x+24$
