Question

Which expression is a factor of 2xy + 6x – 3y – 9?

Answer 1

y – 3

2x – 3

x – 2

2y + 3

Answer 2

2xy + 6x – 3y – 9


(2xy + 6x) + (-3y – 9)


2x(y + 3) + (-3y – 9)


2x(y + 3) - 3(y + 3)


(2x - 3)(y + 3)


So the factors are 2x-3 and y+3


So the answer is choice B

Answer 3

Thankss !

Answer 4

You're welcome

Answer 5

What is the solution set of |x + 5| > 1?

Answer 6

|x + 5| > 1


x + 5 > 1 or x + 5 < -1


x > 1-5 or x < -1-5


x > -4 or x < -6

Answer 7

Simplify (3b2 – 2b + 3) – (5b2 + 4b – 2)

Answer 8

(3b^2 – 2b + 3) – (5b^2 + 4b – 2)


3b^2 – 2b + 3 – 5b^2 - 4b + 2


(3b^2– 5b^2)+(-2b-4b)+(3 + 2)


-2b^2-6b+5



So the answer is -2b^2-6b+5
