Question

One solution of the equation 4x2 − 9x + 5 = 0 is five over four. What is the other solution

Answer 1

it says that x = 5/4 is a solution

i can rewrite it as 4x = 5

and so...4x - 5 is a factor..so just divide that trinomial by 4x - 5 to get the other factor...

Answer 2

then solve for x to find the solution

Answer 3

to find the other solution, solve for r: 5/4*r = 5

r is your other solution... i used the product of the roots is the constant term....
