Find the roots

Find the roots of the algebra expression

h = 36

Evaluate

- 5 h + 84 + 3 h - 12

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

- 5 h + 84 + 3 h - 12 = 0

More Steps

Evaluate

- 5 h + 3 h

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

(- 5 + 3) h

Add the numbers

- 2 h

- 2 h + 84

- 2 h + 84 - 12 = 0

Subtract the numbers

- 2 h + 72 = 0

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

- 2 h = 0 - 72

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

- 2 h = - 72

Change the signs on both sides of the equation

2 h = 72

Divide both sides

\frac{2 h}{2} = \frac{72}{2}

Divide the numbers

h = \frac{72}{2}
