Solve r^2262-1 - ScanMath

Evaluate

r^{2} \times 262 - 1

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

r^{2} \times 262 - 1 = 0

Use the commutative property to reorder the terms

262 r^{2} - 1 = 0

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

262 r^{2} = 0 + 1

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

262 r^{2} = 1

Divide both sides

\frac{262 r ^{2}}{262} = \frac{1}{262}

Divide the numbers

r^{2} = \frac{1}{262}

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

r = \pm \frac{1}{262}

Simplify the expression

More Steps

r = \pm \frac{262}{262}

Separate the equation into 2 possible cases

r = \frac{262}{262} r = - \frac{262}{262}

Solution

r_{1} = - \frac{262}{262}, r_{2} = \frac{262}{262}

Alternative Form

r_{1} \approx - 0.06178, r_{2} \approx 0.06178
