Consider the basis B of R2 consisting of vectors
adelina 88 [10]

The idea is to find a linear combination a_1(5, -6) + a_2(-2, -2) = (-6, 2) It boils down to a system of equations: Take the augmented matrix:

<span>[<span><span>5<span>−6</span></span><span><span>−2</span><span>−2</span></span><span><span>−6</span>2</span></span>]</span> Reduced form: <span>[<span><span>10</span><span>01</span><span><span>−<span>811</span></span><span>1311</span></span></span>]</span> -(8/11)*(5, -6) + (13/11)*(-2, -2) = (-6, 2)
