Hope it Helps !!!

Answer 2

Answer:

$144 {a}^{2} - 156ab + 156ab - 169 {b}^{2} = 144a^{2}$

-156ab and +156ab are cancelled

Now,

$144 {a}^{2} - 169 {b}^{2} = 144a^{2}$

Here,

$144 {a}^{2} \: becomes \: - 144 {a}^{2}$

Then the +144a^2 and -144a^2 are cancelled.

So,

$- 169 {b}^{2} = 0$

or,

${b}^{2} = \frac{0}{69}$

$\sqrt{b} = \frac{0}{ - 169}$

b= 0/169
