Solve (7x-3)4 (7x-3)5

Evaluate

(7 x - 3) \times 4 (7 x - 3) \times 5

To find the roots of the expression,set the expression equal to 0

(7 x - 3) \times 4 (7 x - 3) \times 5 = 0

Multiply the terms

More Steps

20 (7 x - 3)^{2} = 0

Rewrite the expression

(7 x - 3)^{2} = 0

The only way a power can be 0 is when the base equals 0

7 x - 3 = 0

Move the constant to the right-hand side and change its sign

7 x = 0 + 3

Removing 0 doesn't change the value,so remove it from the expression

7 x = 3

Divide both sides

\frac{7 x}{7} = \frac{3}{7}

Solution

x = \frac{3}{7}

Alternative Form

x = 0. \dot{4} 2857 \dot{1}
