SOMEONE PLEASE HELP WITH THESE QUESTIONS!! I don’t mind which one(s) you do I just need as much help as I can get thank you !!

1. Use the FOIL (first, outside, inside, last) method:F: x*x=x^2O: x*-2=-2xI: 3*x=3xL: 3*-2=-6x^2-2x+3x-6*Combine like terms*x^2+x-62. Look for the greatest common factor (GCF) of 15 and 5.  It is 5 (15/5=3 and 5/5=1)5(3x+1)3. You want to find two numbers whose product is 6 and whose sum is -5.  -3 and -2 complete these requirements.(x-3)(x-2)4. Solve for x:*Add x to both sides*y+x=ab*Subtract y from both sides*x=ab-y8. Plug in 0.5 for x and solve:10-8(0.5)10-4610. *Multiply both sides by 5*2x-3=20*Add 3 to both sides*2x=23*Divide both sides by 2*x=23/2I did what I could.  Hope I could help!!
