That doesn't factor neatly. Applying the quadratic equation, we find two imaginary solutions: (-7 plus or minus the square root of -371) divided by 10
x = -0.7 + 1.9261360284258224i
x = -0.7 - 1.9261360284258224i
where i is the square root of negative one.
x(5x + 7)
(5x + 2)(x + 1)
True.
5x2+ 7x + 2 = (x + 1)(5x + 2).
5x2+7x = 12 5x2+7x-12 = 0 (5x+12)(x-1) = 0 x = -12/5 or x = 1
I am assuming this is: .2x4 - 5x2 - 7x, which would be a Quartic Polynomial.
(3b + 7x)(3b + 7x) or (3b + 7x)2
7x + 7 = 7(x + 1)
1
You would factor 2x2 + 7x + 6 into (2x + 3) (x+2)
7x 2= 14
x2 + 7x + 6 = (x + 6) (x + 1)
