Question #03617 Precalculus Matrix Row Operations Solving a System of Equations Using a Matrix 1 Answer Cesareo R. Sep 7, 2016 ((a = -2, b = -7),(a = 0, b = 5)) Explanation: Given p(x) = (1 + x)^5 (1 + a x)^6 = sum_(k=0)^11 c_kx^k we know that c_k = (1/(k!)(d^kp)/(dx^k))_(x=0) so c_1 = 5+6a =b c_2=10 + 30 a + 15 a^2 = 10 Solving for a,b we have two outcomes ((a = -2, b = -7),(a = 0, b = 5)) Answer link Related questions How do I use matrices to solve the system 2x+3y=4 and 5x+8y=11?
