Question

4/3x+1/2=1/1/3
Please solve this equation.​

Answer 1

Answer:

5/8

steps :

4/3 x = 4/3 - 1/2

4/3 x = 8-3/6

4x = 5/6 * 3

4x = 5/2

x = 5/8

Answer 2

Answer:

Given, f(x)=x

4

+3x+1

f

′

(x)=4x

3

+3, it has imaginary root it means f

′

(x)



=0

it means it will cut only at once to x axis.

f(−2)>0,f(−1)<0

So, there exist a root in interval [−2,−1]
