Answer:

5sqrt(5) = q

-5sqrt(5) = q

Step-by-step explanation:

f(q) = q^2 -125

To find the roots set the equation equal to zero

0 = q^2 -125

Add 125 to each side

125 = q^2 -125+125

125 = q^2

Take the square root of each side

±sqrt(125) = sqrt(q^2)

±sqrt( 5*25) = q

±sqrt( 25)* sqrt(5) = q

±5* sqrt(5) = q

±5sqrt(5) = q

If -10 is subtracted from a number, the result is 6. what is the number?

brilliants [131]

Subtracting a negative number is the same as adding a positive number

assume your number is n

n - (-10) = 6
n + 10 = 6

subtract 10 from both sides
