oblicz watrość wielomianu w(x) gdy ; x=√2 , x=-1
w(x)=4x⁴-3x³+x²-5x+3
W( p(2)) = 4 *[ p(2)]^4 - 3* [ p(2)]^3 + [ p(2)]^2 - 5 *p(2) + 3 =
= 4*4 - 3*2 p(2) + 2 - 5 p(2) + 3 = 21 - 11 p(2)
=========================================
p(2) - pierwiastek kwadratowy z 2
W( - 1) = 4*( -1)^4 - 3*(-1)^3 + ( -1)^2 - 5*(-1) + 3 =
= 4*1 - 3*(-1) + 1 + 5 + 3 = 16
