Answer 2

Given:

The equation 2x cube - 3x+ under root 5

To find:

Find the value of 2x cube - 3x+ under root 5 when x is equal to minus 3​

Solution:

From given, we have,

The equation 2x cube - 3x+ under root 5

So, we need to find the value of the above equation, when x is equal to minus 3​.

So, substitute the value of x = -3 in the given equation.

⇒ 2x³ - 3x + √5

⇒ 2 (-3)³ - 3 (-3) + √5

⇒ 2 (-27) + (3 × 3) + √5

⇒ -54 + 9 + √5

⇒ - 45 + √5

Therefore, the value of 2x cube - 3x+ under root 5 when x is equal to minus 3​ is (√5 - 45)
