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.

Q: Xsquared minus 7x plus 10 equals 28?

A equals 4 because 4 plus 6 is 10 or 10 minus 6 is 4.

It can be: 5+10-5 = 10

It is possible.

-7 plus 10 is the same as 10 minus 7, which is 3.

It is possible.

(-45) - (-55) *Minus plus is equals to minus.( -,+ = - ) minus minus is equal to plus (-,- = + ) and plus plus is equal to plus (+,+ = +) so the ans is that, (-45) +55 -45 + 55 (+10)ans Greater value sign has been used, which is 55 so the ans is +10.

-10

You find two numbers whose sum is -7 and product is +10. x2 - 7x + 10 = (x - 2)*(x - 5)

Goes towards positive.for instance, -7 minus -7 = 0or -10 minus -4 = -6OR -25 minus -30 = positive 5

Ten plus ten plus ten minus two hundred equals negative one hundred seventy.
