Question

Find the expression formed by adding -2 to 3 times, the square of x *

Answer 1

Step-by-step explanation:

two to three times the square of X is

Answer 2

Answer:

Required expression is $3 {x}^{2} - 2$

Step-by-step explanation:

Here given,

a expression formed by adding -2 to 3 times, the square of x.

We want to find this expression.

This is a problem of Algebra.

Step by step we can find this.

First square of x $= x \times x = {x}^{2}$

Then,3 times of the square of x = 3 multiplied by x²$= 3 {x}^{2}$

and last we are adding (-2) to 3 times, the square of x and get,

$3 {x}^{2} + ( - 2) \\ = 3 {x}^{2} - 2$

Therefore required expression is $(3 {x}^{2} - 2)$

This is a problem of Algebra.

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)
