Answer 1

`\qquad\qquad\huge\underline{\boxed{\sf Answer}}`

The sign of a will be negative ~

let the value of be be ' -x ' , -x is a negative number (b = -x < 0)

`\qquad \sf  \dashrightarrow \: a * ( - b)/(b)`

`\qquad \sf  \dashrightarrow \: a * ( - ( - x))/( - x)`

`\qquad \sf  \dashrightarrow \: a * ( x)/( - x)`

`\qquad \sf  \dashrightarrow \: a * ( - x)/( x)`

`\qquad \sf  \dashrightarrow \:a * - 1`

`\qquad \sf  \dashrightarrow \:- a`

Therefore, the term a, has a negative sign unless it's value is substituted, I.e -a = 0 ( having no sign )
