Question

quadratic equation(x-7)(x-9)=195​

Answer 1

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

on solving....

${x}^{2} - 9x - 7x + 63 = 195 \\ {x}^{2} - 16x + 63 - 195 = 0 \\ {x}^{2} - 16x - 132 = 0$

This is the quadratic equation.

Given :-

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

====================

To Find :-

Quadratic equation

===================

Solution :-

Multiply (x - 7) by (x - 9)

x² - 9x - 7x + 63 = 195

Taking x term to RHS and another to RHS

x² - 16x = 195 - 63

x² - 16x = 132

x² - 16x - 132 = 0

===================

Hence, we get quadratic equation which is

x² - 16x - 132 = 0
