Let [itex]a_1[/itex] = a column vector with 1, 4, -2; [itex]a_2[/itex] = a column vector with -2, -3, 7; and [itex]b[/itex] = a column vector with entries 4, 1, h.(adsbygoogle = window.adsbygoogle || []).push({});

(I hope this is an adequate description. I forgot how to write pretty matrices in tex ^_^;)

For what values of h is [itex]b[/itex] in the plane spanned by [itex]a_1[/itex] and [itex]a_2[/itex]?

I turned this into an augmented matrix but had trouble reducing it to RREF.
