Question

solve it:
y^2-10y+4=0

.......^_^​

Answer 1

Answer:

${y}^{2} - 10y + 4 = 0 \\ we \: can \: esily \: find \: it \: by \: using \: discreate \: formula \\ we \: hve \: to \: compre \: this \: with \: stndard \: equation \\ a {x}^{2} + by + c = 0 \\ we \: hve \:( a = 1)(b = 10 (c = 4) \\ x =( - b \frac{ + } \: \sqrt{ {b}^{2} - 4ac } ) \div 2a \\ \times = (10 \frac{ + } \: \sqrt{100 + 16} ) \div 2 \\ x =( 10 + \sqrt{116} ) \div 2 \\ x = (10 - \sqrt{116}) \div 2$

hope it helps u mate

and looking nice in pic

Answer 2

Answer:

srry, mate here b=-10, srry, i jst say...i think sooo..if wrong srry,
