Question

please solve this problem 26​

Answer 1

Step-by-step explanation:

$given \: polynomial \: is \: p(x) = 5x - 4 {x}^{2} + 3 \\ \: it \: can \: be \: written \: as \: p(x) = - 4 {x}^{2} + 5x + 3 \\ \: now \: put \: x = - 2 \: then \: \\ \: p( - 2) = - 4( - 2)^{2} + 5( - 2) + 3 \\ \: = > - 4(4) - 10 + 3 \\ \: = > - 16 - 10 + 3 \\ \: = > - 26 + 3 \\ \: = > - 23$

Answer 2

value of 5x-4x²+3 at x=2

= 5×{-2)-4×2²+3

=-10-16+3

=-26+3

=-23
