Question

find the value of the polynomial 5x-4x²+3at​

Answer 1

Answer:

Correct question :-

Find the value of the polynomial 5x - 4x² + 3 at

(1) x = 0

(2) x = - 1

(3) x = 2

Solution :-

(1) x = 0

➪ 5x - 4x² + 3

If x = 0 we get,

➭ 5(0) - 4(0)² + 3

➭ 0 - 0 + 3

➭ 3

(2) x = - 1

➪ 5x - 4x² + 3

If x = - 1 we get

➭ 5(- 1) - 4(- 1)² + 3

➭ - 5 - 4 + 3

➭ - 9 + 3

➭ - 6

(3) x = 2

➪ 5x - 4x² + 3

If x = 2 we get

➭ 5(2) - 4(2)² + 3

➭ 10 - 16 + 3

➭ - 6 + 3

➭ - 3
