To factor this, we can factor both variables and then get a multiplier outside the parentheses and the new variables inside. (Sorry if it’s confusing) 18h = 2*3*3*h 30k = 2*3*5*k Both have 2*3, which is 6. This will be the multiplier. To get the new variables, divide the old variables by 6. 18h/6 = 3h 30k/6 = 5k The signs should not change. 6(3h+5k) Hope this helps!
