Question

The root of equation (x+3)(x+7)/(x-5)(x+3) =1 is​

Answer 1

Answer:

no root

Step-by-step explanation:

$\frac{(x + 3)(x + 7)}{(x - 5)(x + 3)} = 1 \\ (x + 3)(x + 7) = (x - 5)(x + 3) \\ {x}^{2} + 10x + 21 = {x}^{2} - 2x - 15 \\ 10x + 2x = - 15 - 21 \\ 12x = - 36 \\ x = - 3 \\ but \: x = - 3 \: not \: satisfies \: the \: equation \\ so \: no \: root \: of \: the \: euation.$
