Question

Solve:3a^3+4a-3 for which value of 'a' this will zero.

Answer 1

Answer:

Thanks for A2A

Step-by-step explanation:

Susbstituting value of a=0 in the above =n,we get

=>3(0)^3+4(0)-3=0+0-3=-3

Hence,-3 is the answer

Answer 2

Answer:

3a^3 + 4a -3 =0

3a^3 + 4a = 3

a ( 3a^2 + 4 ) = 3

so , a=3 and 3a^2 + 4 = 3

3a^2 = -1

a^2 = -1/3

squareroot of any term is always

greater than or equal to zero

...so this is not possible

SO ANS IS : a = 3
