Question

find the value of the polynomial 3x^3-4x^2+7x-5 when x=2​

Answer 1

Answer:

find the value of the polynomial 3x^(3)-4x^(2)+7x-5, , when x=3 and also when x=-3. Hence , the value of the given polynomial at x=3 and x=-3 are 61 and -143 , respectively.

Answer 2

p(x) = 3(x)3 - 4(x)2 + 7x - 5

p(x) =2

p(2)=3(2)3-4(2)2+7(2)-5

p(2)= 18 - 16 + 14 - 5

p(2)= 11

It's your answer❤
