Given that the equation px^2 + 3px + p + q = 0,where p is not = 0, has two equal real roots,find q in terms of p
the equation has two equal real roots if discriminat is equal to zero
in your case , , and ...factor
solutions: -> exclude because gien that =>=>=>
.......substitute .....both sides multiply by
check if discriminant is equal to zero:
=>true
