x and y are two matrices
x= {-2 0} and y {4 -1}
{5 1} {3 7}
evaluate x^2+y
is the ans={8 -1}
{18 8}
To evaluate the expression x^2 + y, we first need to calculate the square of matrix x and then add it to matrix y.
Matrix x:
-2 0
5 1
To square matrix x, we need to multiply it by itself:
x^2 = x * x
Matrix x * x:
-2 0 -2 0 4 0
5 1 * 5 1 = 25 1 + 5 1 = 26 2
Now, let's add matrix y to the squared result:
4 -1
3 7
+
4 0
+ 26 2
= 30 0
29 9
So, the answer to x^2 + y is:
30 0
29 9
Therefore, the statement that the answer is:
8 -1
18 8
is incorrect. The correct answer is:
30 0
29 9
