Hints....1. a = x, b = 3 2. a = 3x, b = 10... you can always use a box to multiply binomials!3. x has an even power, but 18 is not a perfect square4. 4 is a perfect square and y has an even power#5-8. You can always use the box method with b=0.5. a = 3x, b = 4 6. a=5x, b=87. You must find the gcf of 2 before starting!8. The GCF here is 2x2...then factor!9. A=l*w, so multiply (x-6)(x+6)
