If x equals the square root of ...., then you already have solved for x
40
k = 129
It is: 32.35 minus 10.63 equals 21.72
7
1566 = x
x2-2x-15 = 0 (x+3)(x-5) = 0 x = -3 or x = 5
15x minus 8=minus 180 3x+8=24
Solve this problem -x squared -40x- 80 =0
Solve using the quadratic formula
minus 5
(-1/6) - 2/3 = -0.8333333332
