Question

What are the zeros of f(x)3x+27

Answer 1

Answer:

3x+27=0

3x=-27

x=-27/3

x= -9

Answer 2

Answer:

(-9) is the zero of f(x) = 3x+27

Step-by-step explanation:

Given,

$f(x) = 3x + 27....(1)$

We want to find zeros of f(x).

If

$f(x) = 0$

$3x + 27 = 0$

We are separating variable and constant part.

$3x = - 27 \\ x = \frac{ - 27}{3} \\ x = - 9$

Therefore, required zero of f(x) is (-9)

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
