Can each vector in set of real numbers rℝsuperscript 44 be written as a linear combination of the columns of the matrix a? select the correct choice below and fill in the answer box to complete your choice.
a. no, because the reduced row echelon form of a is
b. yes, because the reduced row echelon form of a is

many reason,

step-by-step explanation:

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
