Consider the matrix:If the eigen values of A are 4 and 8, then _______...
Given,
Sum of eigen values = (A) = 2 + y
Product of eigen values = |A| = 2y − 3x
According to question,
⇒ 4 + 8 = 2 + y
⇒ 2 + y = 12
y = 10…(i)
⇒ 4 × 8 = 2y − 3x
⇒ 2y − 3x = 32…(ii)
Putting y = 10 in equation (ii),
⇒ 2y − 3x = 32
⇒ 20 − 3x = 32
⇒ 3x = −12
x = −4
So, the value of x and y are −4 and 10.
Hence, the correct option is (D).
