Question

Find the value of polynomials of 6x - 3x2 + 2 at: i) x = 0 ii) x = -2 iii) x = -1
and Whether the following are zeroes of polynomial indicated against than, verify:
i) P (x) = lm + m , x = -m/l
ii) P (x) = 3x2 - 1 , x = -1/√3
iii) P (x) = 2x + 1 , x = l/2.

Answer 1

Answer:

p(x) = 6x-3x^2+2

p(0) = 6x0-3x0+2

=2

p(-1) =-6x1-3x1+2

=-9+2

=-7
