Solve using the quadratic formula
16
(b-4) squared
32 + x = 259 + x = 25x = 25 - 9x = 16
2 squared plus 2 squared equals 16 because 2 squared is 4 times 4 equals 16. Math: 4x4=16 so your answer is 16 :)!
By factoring. q2 + 16q = 0 q (q + 16) = 0 Now, either q = 0, or q + 16 = 0. Solve those two equations to get the solution.
x = -8
20
(x + 4)(x +4) or (x + 4)squared
You are describing a circle, with its center at the origin and a radius of 4 (the square root of 16)
h=16
y=16 x= -4
