Answer 1

*Question:-

*If x = -2 then find the value of polynomial 4x + 5x² - 6.*

• 1️⃣ -6
• 2️⃣ 6
• 3️⃣ 8
• 4️⃣ 18

*Answer:-

*Given:-

• x = -2

*To find:-

• the value of polynomial 4x + 5x² - 6.

*Step by Step explanation:-

• x = -2

Putting the value of x in this equation:-

• 4x + 5x² - 6
• 4(-2) + 5(-2)² - 6
• -8 + 5 × 4 - 6
• -8 + 20 - 6
• -8 - 6 + 20
• -14 + 20
• 20 - 14
• 6.

Hence the value of polynomial 4x + 5x² - 6 is 6

The answer is 6.

Answer 2

The value of polynomial 4x + 5x² - 6 when x = -2 is 6.

The value of polynomial

The value of polynomial at a point is find by putting the that value variable in the polynomial.

The given polynomial is 4x + 5x² - 6

The value of polynomial is find when x = -2 , So we need to put the value of  variable x = -2 in the  given polynomial.

The value of 4x + 5x² - 6 = 4 (-2) + 5 (-2)² - 6

                                         =   -8 +  20  - 6

                                         =   6

Thus, The value of polynomial 4x + 5x² - 6 when x = -2 is 6.
