Question

What is the simplified form of the quantity 4 x squared minus 25 over the quantity 2 x plus 5 ?
Answer

2x – 5, with the restriction x ≠ –five over 2

2x + 5, with the restriction x ≠ five over 2

2x – 5, with the restriction x ≠ five over 2

2x + 5, with the restriction x ≠ –five over 2

Answer 1

ok so what bout the restriction

Answer 2

The restriction exists because you are dividing by 2x-5
if x= 5/2 then 2x-5 becomes (put 5/2 in for x) 2*5/2-5= 5-5=0
You are not allowed to divide by 0, so do not allow x= 5/2
restrict x: x≠ 5/2
