Divide everything by 5/7

a=5/7 b=9/10

firstly divide everything by 5/7 x^2 + (63/50)x-(-13/50) = 0 (x+63/100)^2 - 3969/10000 - 13/50 = 0 (x+63/100)^2 = 6569/10000 x = - (63/100)+-sqrt(6569/10000)

then evaluate that .. that should hopefully be right (although i did it in my head, method is sound tho)

got it! just went wrong on one of those huge fractions
anonymous

you are amazing!

alternatively it is usually better instead of dividing it properly by 5/7, to put it outside a large bracket and leave it there, from start; 5/7[x^2+(63/65)x-(13/50) = 0

  • anonymous
forgot end bracket .. but u get the gist
