Answer 2

`\mathbb{PROBLEM :}`

`\tt \: 6. Multiply: ( * - 4)(x + 5)`

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

`\mathbb{ANSWER:}`

`\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \tt \underline \color{green}{x2 + x - 20}`

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

`\mathbb{SOLUTION:}`

`\: \: \: \: \: \: \: \: \tt( * - 4)( * + 5)`

`\: \: \: \: \: \: \: \: \tt = \: x(x + 5) -4(x + 5)`

`\: \: \: \: \: \: \: \: \tt{ = * 2 + 5 * 4 * - 20}`

`\: \: \: \: \: \: \: \: \tt{= x2 + x - 20}`

`\tt \: So \: possible \: Answer \: is : \underline \green{ * 2 + * - 20}`
