Find the value of the polynomial 5x - 4x² + 3 at (i) x = 0 (ii) x = -1 (iii) x = 2

Given polynomial is 5x - 4x² + 3
(i) If x = 0
Let's substitute x = 0 in 5x - 4x² + 3 = 5(0) - 4(0)² + 3 = 0 - 0 + 3 = 3
Therefore, the value of 5x - 4x² + 3 is 3, when x = 0
(ii) If x = -1
Let's substitute x = -1 in 5x - 4x² + 3 = 5(-1) - 4(-1)² + 3 = -5 - 4 + 3 = -6
Therefore, the value of 5x - 4x² + 3 is -6, when x = -1
(iii) If x = 2
Let's substitute x = 2 in 5x - 4x² + 3 = 5(2) - 4(2)² + 3 = 10 - 16 + 3 = -3
Therefore, the value of 5x - 4x² + 3 is -3, when x = 2
