Step-by-step explanation:
5 − 6 2 − 1 3 = 0
− 6 2 − 1 3 + 5 = 0 -6x^2-13x+5=0 −6x2−13x+5=0 − 1
( 6 2 + 1 3 − 5 ) = 0
The value of x is .
Solution:
Given expression is .
Switch both sides.
Subtract 8 from both side of the equation.
Divide by –3 on both side of the equation.
To cancel the cube root, raise the power 5 on both sides.
To find the value of x, take square root on both sides.
Hence the value of x is .
