Answer:(-x-1)(x-4)
Step-by-step explanation:
[tex]-1(x^{2} -3x-4)[/tex]
factor the equation (multiples of 4 are 1 and 4 and 2 and 2) 4-1=1 so the factor you want to use are 1 and 4
-1(x +1)(x-4) -- -4+1=3
distribute the -1 into the first factor
(-x-1)(x-4)
Answer:
[tex]-x^{2}+3x+4[/tex]

Any expression multiplied by 1 remains the same.
2) [tex]-(x^{2}-3x-4)[/tex]
When there is a ' - ' in front of an expression in parenthesis, change the sign of each term in the expression.
3) [tex]-x^{2}+3x+4[/tex]
