If f (x) = 2x2 + 4x − 3, then the quantity f of the quantity x plus h end quantity minus f of x end quantity all over h is equal to which of the following?

the quantity 2 times x plus 2 times h end quantity squared plus the quantity 4 times x plus 4 times h end quantity minus 3 minus the quantity 2 times x squared plus 4 times x minus 3 end quantity all over h
2 times the quantity x plus h end quantity squared plus 4 times x minus 3 minus 2 times x squared minus 4 times x plus 3 all over h
2 times the quantity x squared plus 2 times x times h plus h squared end quantity plus 4 times the quantity x plus h end quantity minus 3 minus the quantity 2 times x squared plus 4 times x minus 3 end quantity all over h
2 times the quantity x plus h end quantity squared plus 4 times the quantity x plus h end quantity minus 3 minus 2 times x squared plus 4 times x minus 3 all over h
