how do we learn to do it its very hard

Question

i cant figure what to combine and how the equation goes im struggling

Answer 1

Well, Reane - you did not give an example of simplifiying that troubles you.... so I willl give you a couple:

1. a lot of HS simplifying is with quadratics, template ax^2 + bx + c = (ax + d)*(x + e)  OK?

thi will work if you can make d*e = c and d + a*e = b, the coefficinet of the the linear x term = hey, it may require a complicated quadratic solution, but Most of the Time it is possible to figure it out; e.g. 

x^2 - 14x + 24 = (x + d)*(x + e) where d*e = 24 and d+e = -14 

well what two numbers add up to 14 and have a product of 24?

YES! 12 and 2, but both have to negative to yield the  negative 14 

so, the simplification is (x - 12) *( x - 2);

not bad, right?
