Step-by-step explanation:

1. Both and 64 are perfect squares, meaning is twice the product of x and 8. Since all signs are positive, the equation would be: . Let and . or .

2. Since -3 is a factor of all 3 terms, factor out the -3 which makes,   . K is also a common factor, so you would factor that out too, . Then simply, find the two factors whose product is -2 and whose sum is -5. .

3. By factoring , you would break the expressions in the group=. Then, factor out "x" from . Factor out "5" from = . Finally, factor out the common term "3x-1" =
