You can put this solution on YOUR website! Factor the expression.
10y^2 - 29y + 10
-----
Think of 2 numbers whose product is 10*10 = 100 and whose sum = -29
Ans: -25 and -4
----
Rewrite the problem replacing the middle term::
10y^2 - 25y-4y + 10
Factor::
5y(2y-5)-2(2y-5)
----
Factor Again to get ::
= (5y-2)(2y-5)
