Can you help me solve the second IRR, i was having trouble getting it. Please show all the relevant steps. Thank you!

Because the total cash flows are equal to zero (-$98 million + $ 14 million x 20 - $182 million = 0), one IRR must be 0%. Because the cash flows change sign more than once, we can have a second IRR. This second IRR solves: $14 million x 1 1 (1 + r)20 NPV = - $98 million + $182 million (1+r)21 (1 + r)
