Question

Example 2 : Find the value of each of the following polynomials at the indicated value
of variables:
(i) p(x) = 5x2 – 3x + 7 at x = 1.
(i) qb) = 3y3 – 4y + V11 at y = 2.
(iii) p(t) = 4r + 5+ - + + 6 at t = a.​

Answer 1

Answer:

(i)=> p(x) = 5x2-3x+7

p(1)=5×1×2-3×1+7

=6×2-3×1+7

=12-3+7

=12-10

=2
