Express each cubic function below in terms of linear factors.a)f(x)=x³-6x²-27xb)f(x)=x³-16x²c)f(x)=x³+16x²

nirvana33 [79]

Answer:

a) x (x-9) (x+3)

b) x (x+4)(x-4)

c) (x)(x)(x + 16)

Step-by-step explanation:

We're going to equal the functions to zero and find their roots by factorizing:

a) f(x)=x³-6x²-27x

x³-6x²-27x = 0

x(x²-6x-27) = 0

⇒x (x-9) (x+3)

b) f(x)=x³-16x

x³-16x = 0

x (x²-16) =0

⇒x (x+4)(x-4)

c) f(x)=x³+16x²

x³ + 16x² = 0

x² ( x +16)

⇒(x)(x)(x + 16)

Please help i need this done asap

ki77a [65]

Answer:

A

Step-by-step explanation:

Using the rules of exponents

$a^{m}$ × $a^{n}$ = $a^{(m+n)}$ , $a^{-m}$ = $\frac{1}{a^{m} }$ , $a^{0}$ = 1

(14x³ $y^{-4}$ )(4 $x^{-5}$ $y^{4}$ )

= 14 × 4 × x³ × $x^{-5}$ × $y^{-4}$ × $y^{4}$

= 56 × $x^{(3-5)}$ × $y^{(-4+4)}$

= 56 × $x^{-2}$ × $y^{0}$

= 56 × $\frac{1}{x^2}$ × 1

= $\frac{56}{x^2}$ → A
