Step-by-step explanation:

• 5x-4x²+3
• p(x) = -4x^2+5x+3
• g(x) =x=-2
• put p(x) = -2
• p(-2) = -4×(-2)^2 + 5×(-2) + 3
• = -4×4 -10 +3
• -16 -10 +3
• -26+3
• -23

so, the value of the polynomial 5x-4x²+3 when x=-2. is -23

may I hope this answer help u

Answer 2

Step-by-step explanation:

p(x) =5x-4x²+3

p(-2)=5(-2)-4(-2)²+3=-10-4(4)+3=-10-16+3=-26+3=-23
