x2 - 7x = 0
The left side is the product of x(x-7).
The equation is true if either factor is zero.
So the equation has 2 solutions:
1). X = 0
2). X = 7
40
7
It is: 32.35 minus 10.63 equals 21.72
15x minus 8=minus 180 3x+8=24
Solve using the quadratic formula

k = 129
7
It is: 32.35 minus 10.63 equals 21.72
1566 = x
E is energy and MC2 is matter used to the second power... now you solve it
15x minus 8=minus 180 3x+8=24
Solve this problem -x squared -40x- 80 =0
Solve using the quadratic formula
There is a formula for "the difference of squares." (x + 7)(x - 7) = 0 x = 7, -7
