Which expression is the result of solving the equation ax-b=cy for x (For a0)

x = (cy+b)/a

Step-by-step explanation:

ax-b=cy

Add b to each side

ax-b+b=cy+b

ax = cy +b

Divide each side by a

ax/a = (cy+b)/a

x = (cy+b)/a

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
