x2 - 7x + 10 = 28; whence,
x2 - 7x - 18 = 0, and
(x - 9)(x + 2) = 0.
The above is true exactly when, either,
x - 9 = 0, or
x + 2 = 0.
Therefore, the solution is:
x = 9 or -2.
Checking,
92 - (7)(9) + 10 = 81 - 63 + 10 = 28; and
(-2)2 - (7)(-2) + 10 = 4 + 14 + 10 = 28;
verifying the solution found above.
