If: y = kx+1 is a tangent to the curve y^2 = 8x Then k must equal 2 for the discriminant to equal zero when the given equations are merged together to equal zero.
one squared equals one.
1 squared radical 40 is equal to 1 squared radical (4 x 10), and this become 2 squared radical 10. By adding 2 squared radical10 with 3 squared radical 10 we get 5 squared radical 10.
i = sqrt of (-1) ( imaginary) i squared = sqrt(-1) x sqrt (-1) = -1 (minus one)
This expression factors as x -1 quantity squared.
