20Y^4-33Y+10
(5Y-2)(4Y-5) ANSWER.
-------------------------------
X^2+X+6
THIS EQUATION CAN BE FACTORED USING THE QUADRATIC EQUATION THUS:
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
X=(-1+-SQRT]1^2-4*1*6])/2*1
X=(-1+-SQRT[1-24])/2
X=(-1+-SQRT-23)/2
X=(-1+-4.796)i/2
X=(-1+4.796i)/2
X=1/2+4.796i/2
X=.5+2.398i ANSWER.
X=(1-4.796i)/2
X=.5-2.398i ANSWER.
