1)please answer the whole questions in full

2)please use the stated method of approach

a value is 5

b value is 3

2. Consider the following problem. Maximize Z= (a + b)x+2bx2, subject to bx + ax2 10 x + bx = 20 and 220, 2 unconstrained in sign. (1) Use Table 6.12 to convert the primal problem to our standard form given at the beginning of Sec6.1, and construct the corresponding dual problem. (2) Use the SOB method to construct the dual problem. Then show that this dual problem is equivalent to the one obtained in part (1)
