Answer:
3x^2 + xy - 10y^2
Step-by-step explanation:
1. Use the FOIL method
3x
^2 − 5xy + 6yx − 10y
^2
2. Collect like terms
3x
^2
+ (−5xy + 6xy) − 10y^2
3. Simplify
3x
^2
+ xy − 10y^2
Answer:
b 2o i think sorry if its wrong
Answer:
P = - 3
Step-by-step explanation:
For the equation to have no solutions the the coefficient of x on both sides must be the same.
5 - 3x = Px + 7 ← P = - 3 , then
5 - 3x = - 3x + 7 ( subtract 5 from both sides )
- 3x = - 3x + 2 ( add 3x to both sides )
0 = 2 ← not possible
Meaning the equation has no solutions
