(10x + 1)(x + 10)
That's not a trinomial, but it factors to x(x + 19)
I think that wants to be 16x2 - 40xy + 25y2 That factors to (4x - 5y)(4x - 5y) or (4x - 5y)2
That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: (-615 plus or minus 15 times the square root of 3281) divided by 2. x = 122.10010474859058 x = -737.10010474859058
This is the generalized trinomial equation (aka quadratic):y = ax2 - bx - cBefore factoring, always check the discriminant of the quadratic equation, which is:b2 - 4acIf it is a rational square (16, 25, 196, 225), then it is factorable. If it is not, then it is not factorable.In this case, it is not, since the discriminant is equal to 2√3.Now, you will have to use the quadratic formula:(-b2 +/- √(b2 - 4ac))/2This will give you (14 +/- 2√3)/2
