This method allows me to quickly see the solution. My precalc teacher called me a factoring master, but its only because I learn from the master!
PS: just got my 2.718 t-shirt today, can't wait to wear it to school tomorrow. 😂

In high school, we used the Product Sum Choose method, it works best for monic quadratics. This is more visual :)

I could'nt do this but now I can thanks!
As always.

Think of two number when you multply you get the product of a×c and thier sum is b and then break b to those number and factor by grouping

4x+4x-3
= 4x+6x-2x-3
= 2x(2x+3)-1(2x+3)
=(2x+3)(2x-1)


4x^2-5x-6
=4x^2-8x+3x-6
=4x(x-2)+3(x-2)
=(x-2)(4x+3)

Is the answer still correct if the parentheses are flipped so (2x+3)(2x-1)?

What about when they have an extra letter?
