Question

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

Answer 1

4x^2 - 4x - 5x + 5 = 0
4x(x-1) -5(x-1) = 0
(x-1)(4x-5) = 0

The other solution is x = 1

Answer 2

that means that one bracket is ( 4x - 5) so the other must b (x - a) - can u see what a must be?

Answer 3

Trick: Sum of the coefficients is 0, hence 1 is a solution ;-)

Answer 4

good trick
