If `[(a+b,2),(1,a-b)]=[(3,2),(1,7)]`, then find the values of a and b.

If a =-2, b=0, find the value of (a+b)^2 and a^2-ab+b^2

If the points (a,0), (0,b) and (1,1) are collinear,then find the value of 1/a+1/b

If A=[(1,1),(1,1)] and B=[(2,-1),(0,1)] , find 2A+3B .

If A=[(2,-1),(3,2)] and B =[(0,4),(-1,7)] , then find 3A^(2) -2B+1 .

If A = [(-2, 3),(1,2)] and B = [(-1, 0),(1, 2)] then find (A + 2B) .

if f(x)={(x^2,xle1),(ax+b,x>1):} is differentiable at x = 1, find the values of a and b. Hence find f'(1)

If A=[{:(-2,3),(1,2):}] and B=[{:(-1,0),(1,2):}] , then find (A+2B)' .

If A(5,-1),B(-1,7) and C(1,2) are the verticles of a triangle find the equation of the internal bisector of angleA

If A=[(1,2),(3,4)], B=[(2,1),(4,3)] , find (A-B)(A+B) and A^2-B^2 .

if a+b+c=9 and a^2+b^2+c^2 =35,then find the value of a^3+b^3+c^3-3abc
