Question

$240 = {x } ^{2} - 14x$
​

Answer 1

Answer:

${x}^{2} - 14x = 240 \\ \\ {x}^{2} - 14x - 240 = 0 \\ \\ {x}^{2} - 24x + 10x - 240 = 0 \\ \\ {x}(x - 24) + 10(x - 24) = 0 \\ \\ (x - 24)(x + 10) = 0 \\ \\ = > x = 24 \: or \: - 10 \\ \\ \\ hope \: it \: helps \: u.....$

Answer 2

$given \\ equation \\ 240 = {x}^{2} - 14x \\ = > {x}^{2} - 14x - 240 = 0 \\ = > {x}^{2} - 24x + 10x - 240 = 0 \\ = > x(x - 24) + 10(x - 24) = 0 \\ = > (x + 10)(x - 24) = 0 \\ = > x + 10 = 0 \\ = > x = - 10 \\ = > x - 24 = 0 \\ = > x = 24 \\ hence \: x = - 10and24$
