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