Evaluate
(7x−6)(8x3)
To find the roots of the expression,set the expression equal to 0
(7x−6)(8x3)=0
Multiply the terms
(7x−6)×8x3=0
Multiply the terms
8x3(7x−6)=0
Elimination the left coefficient
x3(7x−6)=0
Separate the equation into 2 possible cases
x3=07x−6=0
The only way a power can be 0 is when the base equals 0
x=07x−6=0
Solve the equation
More Steps

Evaluate
7x−6=0
Move the constant to the right-hand side and change its sign
7x=0+6
Removing 0 doesn't change the value,so remove it from the expression
7x=6
Divide both sides
77x=76
Divide the numbers
x=76
x=0x=76
Solution
x1=0,x2=76
