SOLUTION: if x=3 what is the evaluation for this polynomial 2x^3-3x^2+1

Question 625205: if x=3 what is the evaluation for this polynomial

2x^3-3x^2+1
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
Replace x with 3 and evaluate

2x^3-3x^2+1

2(3)^3-3(3)^2+1

2(27)-3(9)+1

54-27+1

28

So 2x^3-3x^2+1 = 28 when x = 3
