Question

(x-7)(x-9) =195 by quadratic equation ​

Answer 1

$\large \blue \star \: \sf \fbox \green{Answer - }$

$\sf \: (x-7)(x-9) =195$

$\sf \longrightarrow \: x(x - 9) - 7(x - 9) = 195$

$\sf \longrightarrow \: {x}^{2} - 9x - 7x + 63 = 195$

$\sf \longrightarrow \: {x}^{2} - 16x + 63 = 195$

$\sf \longrightarrow \: {x }^{2} - 16x + 63 - 195 = 0$

$\sf \longrightarrow \: {x}^{2} - 16x - 132 = 0$

$\sf \:hope \: its \: helpful........$

Answer 2

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

2

=》 x - 9x - 7x + 63 = 195

2

=》x -16x +63 = 195

2

=》x - 16 x + 63 - 195 = 0

2

=》x - 16 x - 132 = 0
