Find the roots

Find the roots of the algebra expression

h = \frac{1}{7}

Alternative Form

h = 0. \dot{1} 4285 \dot{7}

Evaluate

- 2 h + 1 + 23 h - 4

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

- 2 h + 1 + 23 h - 4 = 0

- 2 h + 1 + 23 h

Add the terms

More Steps

Evaluate

- 2 h + 23 h

Collect like terms by calculating the sum or difference of their coefficients

(- 2 + 23) h

Add the numbers

21 h

21 h + 1

21 h + 1 - 4 = 0

Subtract the numbers

21 h - 3 = 0

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

21 h = 0 + 3

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

21 h = 3

Divide both sides

\frac{21 h}{21} = \frac{3}{21}

Divide the numbers

h = \frac{3}{21}

Solution

h = \frac{1}{7}

Alternative Form

h = 0. \dot{1} 4285 \dot{7}
