show that object's horizontal range is

(a²+ab+b²)m/(a+b)

what I did was:

O-A

bm=V cos Θ*t

t=x/V cos Θ

O-A

am=v Sin Θ*t-g/2*t²

am=V sin Θ(bm/V cos Θ)-g/2 *(bm/V cosΘ)²

A-B

am=V cos Θ*t

t=x/V cos Θ

A-B

bm=v Sin Θ*t-g/2*t²

bm=V sin Θ(am/V cos Θ)-g/2 *(am/V cosΘ)²

got two equations.but now what??

Thank you for your time
