Helping hand read the hint it is 32.48
26/10 = 2.60 .... 2.60 x 30 = 78. So 78 is the answer
To factor by grouping, you group up the 1st 2 terms together and the last 2 terms together and then factor those pieces.
(x^3 + x^2) + (x + 1)
x^2(x + 1) + 1(x +1) - now factor out the (x + 1)
(x + 1)(x^2 + 1) - final answer
