number and nature of solutions for 4k^2-8k+3 = 0 by finding the discriminant
the discriminant sqrt%28+b%5E2-4%2Aa%2Ac+%29+ 0f 4k^2-8k+3 = 0 where a = 4, b = -8, c = 3
sqrt%28+b%5E2-4%2Aa%2Ac+%29+ = sqrt%2864+-+48%29+=+sqrt%2816%29+=+4
number and nature of solutions: 2 real roots , discriminant = 4 and is > 0
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+ Quadratic Formula for ax%5E2+%2B+bx+%2B+c
x is k in this problem...
k+=+%288+%2B-+4%29%2F%288%29+=+1+%2B-+%281%2F2%29
k = 1/2, 3/2 (the two real solutions)
