Solve h^2697-1-0 - ScanMath

Question

Simplify the expression

697 h^{2} - 1

Evaluate

h^{2} \times 697 - 1 - 0

Use the commutative property to reorder the terms

697 h^{2} - 1 - 0

Solution

697 h^{2} - 1

Show Solution

h_{1} = - \frac{697}{697}, h_{2} = \frac{697}{697}

Alternative Form

h_{1} \approx - 0.037878, h_{2} \approx 0.037878

Evaluate

h^{2} \times 697 - 1 - 0

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

h^{2} \times 697 - 1 - 0 = 0

Use the commutative property to reorder the terms

697 h^{2} - 1 - 0 = 0

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

697 h^{2} - 1 = 0

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

697 h^{2} = 0 + 1

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

697 h^{2} = 1

Divide both sides

\frac{697 h ^{2}}{697} = \frac{1}{697}

Divide the numbers

h^{2} = \frac{1}{697}

Take the root of both sides of the equation and remember to use both positive and negative roots

h = \pm \frac{1}{697}

Multiply by the Conjugate

\frac{697}{697 \times 697}

When a square root of an expression is multiplied by itself,the result is that expression

\frac{697}{697}

h = \pm \frac{697}{697}

Separate the equation into 2 possible cases

h = \frac{697}{697} h = - \frac{697}{697}

Solution

h_{1} = - \frac{697}{697}, h_{2} = \frac{697}{697}

Alternative Form

h_{1} \approx - 0.037878, h_{2} \approx 0.037878
