Answer:
Solving the expression [tex]vx+7v-3x-21[/tex] using factor by grouping we get [tex]\mathbf{(x+7)(x-3)}[/tex]
Step-by-step explanation:
We need to solve the expression [tex]vx+7v-3x-21[/tex] using factor by grouping
Factor by grouping requires to group first two terms together and last two terms together and try to find out the common numbers in the groups.
We can group:
[tex](vx+7v)(-3x-21)[/tex]
Taking v common from first group and -3 from second
[tex]v(x+7)-3(x+7)[/tex]
Taking x+7 common
[tex](x+7)(x-3)[/tex]
So, Solving the expression [tex]vx+7v-3x-21[/tex] using factor by grouping we get [tex]\mathbf{(x+7)(x-3)}[/tex]
