Question

if x=1/2 is a zero of a polynomial 3x^3+ax^2-4x+3 find value of a

Answer 1

Answer:

Step-by-step explanation:

3x^3+ax^2-4x+3=0[given x=1/2]

=>9x^+2ax^-4x+3=0

=>9(1/2)^+2a(1/2)^-4×1/2+3=0

=>9×1/4+2a1/4-2+3=0

=>9/4+2a/4-1=0

=>9+2a-4/4=0

=>9+2a-4=0

=>2a+13=0

=>2a=-13

Therefore,a=-13/2
