5/8(x-5)^2 -6 this equation is in vertex, i need it in standard form . algebra 1 desperate.

Expand the factor in the brackets

y = 5/8* (x^2 - 25x + 25) - 6

Multiply through by 5/8

y = 5/8 x^2 - (5/8)*25x + 5/8 * 25 - 6    Change the 6 to 8ths

y = 5/8x^2 - (5/8)*25x + 125/8 - 48/8 Combine the 2 fractions at the end.

y = (5/8)x^2 - 5/8*25x + 77/8              Multiply 5/8 * 25

y = (5/8)x^2 - (125/8)*x  + 77/8
