Answer 1

the equation should be in the form

ax^2 + bx = c

where the coefficient a is either 1 OR can be factored to be 1 without creating fractions

I hope that makes sense, lmk if you're still stick

Answer 2

that's a good guess but not quite, if we try to factor out that 5 at the beginning we get

5(x^2 + 3x/5) = 9 which is technically solvable using the completing the square but difficult to work with algebraically

there's one that's a little easier to work w/

Answer 3

there's another one in a similar format, where the leading coefficient is already 1

Answer 4

awesome, well done
