One of the solutions to x2 − 2x − 15 = 0 is x = −3. What is the other solution?

Alex_Xolod [135]

If you factor the equation you can see what the solutions are. Two factor a quadratic of the form ax^2+bx+c, find two values which satisfy two conditions...

jk=ac=-15 and j+k=b=-2 so j and k must be -5 and 3 so the factors are:

(x-5)(x+3)

So the other solution is x=5
