Question

Sum of the values of the polynomial
p(x) = x - 3x² + 2x - 1 at x = 1 and x = 2 is

Answer 1

Answer:

p(1)=1-3(1)*2+2(1)-1

=1-3+2-1

=-4+3= -1

p(2)=2-12+4-1

=-13+4=-9

Answer 2

Answer:

x - 3x^2 + 2x - 1

If x=1

1-3*1^2+2*1-1

=1-3+2-1

= -1

If x=2

2-3*2^2+2*2-1

=2-12+4-1

= -6

Sum of values= -1-6 = -7
