For this case we must simplify the following expression:
[tex]3x-7- (4x ^ 2-2x-5)[/tex]
According to the law of multiplication signs we have:
[tex]- * + = -\\- * - = +[/tex]
So, we have:
[tex]3x-7-4x ^ 2 + 2x + 5 =[/tex]
We add similar terms:
[tex]3x + 2x-7 + 5-4x ^ 2 =[/tex]
Equal signs are added and the same sign is placed.
Different signs are subtracted and the major sign is placed.
[tex]5x-2-4x ^ 2 =[/tex]
We order the expression:
[tex]-4x ^ 2 + 5x-2[/tex]
ANswer:
[tex]-4x ^ 2 + 5x-2[/tex]
