Question

-x(-x)=x for x = -7/15 i am stuck pls help

Answer 1

Answer:

-x(-x)=x

-7/15×-7/15=-7/15

49/125=-7/15

49/125+7/15

48+105/125

=153/125

Answer 2

Answer:

$given \: \: \: \: x = \frac{ - 7}{15}$

$- x( - x) = x$

${x}^{2} = x........(i)$

putting the value of x in the equation....(i)

$( \frac{ - 7}{15} ) ^{2} = \frac{ - 7}{15}$

$\frac{49}{225} = \frac{ - 7}{15}$

$49 \times 15 = - 7 \times 225$

$732 = - 1575$

$= -230 7$
