x = 1, y = 2. (2 = 3 - 1, 1 + 4 = 5)
Solve this problem -x squared -40x- 80 =0
5.
If r-squared = theta then r = ±sqrt(theta)
root 7
h = +11 and/or -11
Solve using the quadratic formula
If x squared -10 = 0 then x = the square root of 10
Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.
X=1
(x-5)(x+3)
(x-3)(x-2)
(x - 3)(x + 5)
