Answer:
Step-by-step explanation:
Given:
We need to reduce the given matrix to reduced echelon form.
Solution:
Make zeroes in column 1 except the entry at row 1, column 1. As we can see all elements in column are already zero. Make zeroes in column 2 except the entry at row 2, column 2.
So, in reduce echelon form is
X^2 + 13x + 50
= x^2 + 8x + 5x + 40
= x(x + 8) + 5(x + 8)
= (x + 5)(x + 8)
2.74 and 137/50 should be correct
Answer:
too small
