Q5 of 40 Page 18

Find the oral solution of the equation by the formula paravartya Yojayet.

(x + 7) (x + 9) = (x – 8) (x – 11)


As per the formula of Parvartya Yojayet, its application is used as –


(x + a) (x + b) = (x + c) (x + d)



So comparing the equations,


a = 7, b = 9, c = -8 & d = -11
