Question

write a quadratic equation with the given roots in ax^2+bx+c=0 form (5/4) and 9

Answer 1

sum of roots = -b/a
product of rots = c/a

so here we get:
5/4 + 9 = -b/a so 41/4 = -b/a
45/4 = c/a

Answer 2

or as an alternative method,
having 5/4 and 9 as roots means the they are solutions to this equation:
\(\large (x-\frac{5}{4})(x-9)=0 \)
all you need to do is multiply it out....

Answer 3

yes - why didn't i think of that!!??

Answer 4

lol well thanks for the help guys...but it doesn't really answer the question..i need to write an equation for specific roots....not to solve
