Answer 2

use the discriminant

Answer 3

factor 2
turn into a(x-b)^2+c

Answer 4

2x^2+4x+4
=2 {x^2+2x+2}
=2{(x+1)^2-1+2}

Answer 5

its

b^2 -4ac

if

b^2 - 2ac > 0 2 unequal real roots, if its a perfect square, the 2 roots are rational

b^2 - 4ac = 0 2 equal real roots

b^2 - 4ac < 0 2 complex roots
