Find scalars a and b such that z ax + by

WebFind scalars a and b such that u = av +bw. Solution: We need to find scalars a and b such that h2,1i = ah1,1i+bh1,−1i, which turns to h2,1i = ha,ai+hb,−bi = ha+b,a−bi. The first coordinates of the two vectors must be equal to one another, and so must the second coor-dinates. Hence we get a system with two unknowns, a and b, and two ... WebFind a basis for W. Solution. Any polynomial in P 3(R) is of the form f(x) = a+bx+cx2+dx3. The given equations imply that a = b ...

WebJun 9, 2024 · I did the following: $A.X = B$ Since $Det (A) ≠ 0$, $A$ is reversible. Then, I multiply on both sides of the equality to the left by the inverse of $A$. We obtain: $A^ {-1} .A.X = A^ {-1}.B$. Then, $X = A^ {-1}$. Now, since the inverse of a matrix is unique then the system has a single solution.
