Question

discrminate of -×2+1/2×+1/2=0 pls answer this​

Answer 1

-2+1/2*1/2

-2+1/4

-8+1/4

-7/4 answer

Answer 2

$-x ^{2} + \frac{1}{2}x + \frac{1}{2} = 0 \\ \frac{ - 2x^{2} + x + 1 }{2} = 0 \\ -2 x ^{2} + x + 1 = 0$

a= -2

b=1

c=1

$d = \sqrt{b ^{2} - 4ac} \\ d = \sqrt{1 ^{2} - 4 \times - 2 \times 1} \\ d = \sqrt{1+ 8} \\ d = \sqrt{9}$
d=3

thnxx

hope it helps you
