=> x^2 + (m+5)x - (m+2)x - (m+2)(m+5) = 0
=> x (x + m+5) - (m+2)(x+m+5) = 0
=> (x+m+5)(x-m-2) = 0
=> x = - m-5. and m+2
Roots are (-m-5) and (m+2)
when two parallel lines are cut by a transversal then the angles formed between them are vertical angles corresponding angles etc..
i that answer is understandable for god
