B squared -4ac is the discriminant. you get 0, which means it will have one rational solution.
1^2 + 1^2 + 1^2 + 1^2 + 1^2 + 1^2 = 1 + 1 + 1 + 1 + 1 + 1 = 5
x = -½
That factors to (a + 1)(a + b) a = -1, -b b = -a
X=1/2
-x2+2.5x+1=0 x=-0.350781 x=2.85078
3x(2x + 1)
x^2 + x = 0 x(x+1) = 0 x = 0 and x = -1
(2x-4)(x-1) = 0
x2+12x+11=0 (x+11)(x+1)=0 x=-11 or x=-1
1 squared plus 8 squared or 4 squared plus 7 squared
