Question

(x-7) (x-9)=195 please step by step show​

Answer 1

Hey mate,

Here's your answer.. ☺

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

${x}^{2} - 9x - 7x + 63 = 195$

${x}^{2} - 16x + 63 = 195$

${x}^{2} - 16x + 63 - 195 = 0$

${x}^{2} - 16x - 132 = 0$

$solving \: by \: quadratic \: equation \: method$

$x = 6 \: or \: x = ( - 22)$

Hope it helps. ❤
