Type your math problem... p^2-98

Question

Find the roots

p_{1} = - 72, p_{2} = 72

Alternative Form

p_{1} \approx - 9.899495, p_{2} \approx 9.899495

Evaluate

p^{2} - 98

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

p^{2} - 98 = 0

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

p^{2} = 0 + 98

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

p^{2} = 98

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

p = \pm 98

Simplify the expression

Write the number in exponential form with the base of 7

7^{2} \times 2

The root of a product is equal to the product of the roots of each factor

7^{2} \times 2

Reduce the index of the radical and exponent with 2

72

p = \pm 72

Separate the equation into 2 possible cases

p = 72 p = - 72

Solution

p_{1} = - 72, p_{2} = 72

Alternative Form

p_{1} \approx - 9.899495, p_{2} \approx 9.899495
