What should come in place of question mark (?) in the following question ?
$$(78.95)^{2}-(43.35)^{2}=?$$
In each of these question two equations I & II with variables a & b are given You have to solve both the equations to find the values of a & b
Mark answer if
a) a<b
b) $$a\leq b$$
c) relationship between a & b cannot be established
d) a>b
e) $$a\geq b$$
I.$$2a^{2}+a-1=0$$
II.$$12b^{2}-17b+6=0$$
I.$$a^{2}-5a+6=0$$
II. $$2b^{2}-13b+21=0$$
I.$$a^{2}+5a+6=0$$
II.$$b^{2}+7b+12=0$$
I.$$16a^{2}=1$$
II.$$3b^{2}+7b+2=0$$
I.$$a^{2}+2a+1=0$$
II.$$b^{2}=\pm4$$
