Answer 1

Step-by-step explanation:

Given We need to find the value of x in the matrix.  

• Now A x B x C = 1 x 3  3 x 3  3 x 1 = [A] [B][C] = [0]
• [1 + 2x + 15       3 + 5x + 3        2 + x + 2] [1
•                                                                  2     = 0
•                                                                  x]  
• 2z + 16           6 + 5x         4 + x] [1 2  x] = [0]
• [2x + 16           6 + 5x         4 + x] [1   2    x]
• So 2x + 16 + 12 + 10x + 4x + x^2 = 0
• So we get x^2 + 16x + 28 = 0
• So x^2 + 14x + 2x + 28 = 0
• So x (x + 14) + 2(x + 14) = 0
• So x + 14 = 0 or x + 2 = 0
• So x = - 14 . -2
