Question

solve (x - 7) ( x - 9)= 195

Answer 1

x²-16x+63=195,

x²-16x+63-195=0,

x²-16x-132=0,

x²-(22-6)x-132=0,

x²-22x+6x-132=0,

x(x-22)+6(x-22)=0,

(x-22)(x+6)=0,

Answer 2

heya mate ...........♥️♥️

step by step explanation:

(X - 7) (X - 9) = 195

or, x² - 9x - 7x + 63 =195

or, x²- 16x + 63 - 195 = 0

or, x² - 16x - 132 = 0

or, x²- ( 22 - 6 )X - 132 = 0

or, x² - 22x + 6x - 132 = 0

or, X ( X - 22 ) + 6 ( X - 22 ) = 0

or, (X - 22) (X + 6) = 0 _ANS.
