first add 27x to each side 20x^2 +27x + 14 = 0

oh no, you can't subtract 20x^2 and 27x one is x to the second power

it's 20x^2 + 27x + 14 = 0 the 27 has a variable of x which we don't know what is so we can't add or subtract with it unless another number has the same variable

ok, so if your adding or subtracting with a variable you need to have the same variable, but if your multiply or dividing it doesn't matter.

Sorry, I got kicked off the site and lost everything I had typed. This doesn't factor into something easy with integer values... 20x^2 +27x + 14 = 0 you can divide it all through by 20 to get: x^2  (27/20)x + (14/20) = 0 But in my opinion, that's not much better. The solutions are x = 8/20 and x = 35/20 which both reduce to x = 2/5 and x = 7/4 that means you could have factored it as: (x + 2/5)(x  7/4) = 0 If you can see how to easily get from the original quadratic equation to this factored form, then great. Personally, it doesn't seem easy or obvious to me, and if the problem hadn't stated to solve by factoring, I would have used the quadratic formula to get the solutions for x.
