# Given A = [(3,-2),(-1,4)] B = [(6),(1)], C = [(-4),(5)] and D = [(2),(2)] Find Ab + 2c - 4d - ICSE Class 10 - Mathematics

#### Question

Given A = [(3,-2),(-1,4)] B = [(6),(1)], C = [(-4),(5)] and D = [(2),(2)] Find AB + 2C - 4D

#### Solution

AB = [(3,-2),(-1,4)][(6),(1)] = [(18-2),(-6+4)] = [(16),(-2)]

AB + 2C - 4D = [(16),(-2)] + [(-8),(10)] - [(8),(8)] = [(0),(0)]
