Question

for polynomial p(x)=6x³+29x²+44x+21 find p(-2)

Answer 1

p(-2) = 6(-2)^3 +29(-2)^2 +44(-2)+21
=6(-8) +29(4)-88+21
=-48+116-88+21
137-88-48
137-136
1 is answer obtained

Answer 2

p(x)=6x³+29x²+44x+21
p(-2)= 6* (-2)^3 + 29* (-2)^2 +44*(-2)+21
= 6*( -8)+ 29 * (4) -88 +21
= -48 + 116 -88 +21
= 137. - 136 = 1
