Show that A=[[-8,5],[2,4]] satifies the equation x^2 +4x-42=0

If A=[(-8,5),(2,4)] satisfies the equation f(x)=x^(2)+4x-p=0 then p=

Show that A = [(-8,5),(2,4)] satsfies the equation x^2 + 4x - 42= 0 . Hence find A^-1

If the arithmetic mean and geometric mean of the p^(th) and q^(th) terms of the sequence -16,8,-4,2,… satisfy the equation 4x^2-9x+5=0 , then p+q is equal to "______"

Consider the matrix A=[(-8,5),(2,4)] Show that 'A' satisfies the equation x^2+4x-42=0

If X=[{:(3,-4),(1,-1):}],B=[{:(5,2),(-2,1):}]and A=[{:(p,q),(r,s):}] satisfy the equation AX = B, then the matrix A is equal to

If p is the smallest value of x satisfying the equation 2^(x)+(15)/(2^(x))=8 then the value of 4^(p) is equal to 9(b)16(c)25(d)1

If -4 is a root of the equation x^(2)+px-4=0 and if the equation x^(2)+px+q=0 are equal roots, find the values of p and q.

If cos^(4)theta+p, sin^(4)theta+p are the roots of the equation x^(2)+a(2x+1)=0 and cos^(2)theta+q,sin^(2)theta+q are the roots of the equation x^(2)+4x+2=0 then a is equal to
