Question

4x²+¼y²+⅑z²-2xy+⅓yz-(4/3)zx When x= -1, y= -½, z= 3​

Answer 1

Step-by-step explanation:

4x²+¼y²+⅑z²-2xy+⅓yz-(4/3)zx When x= -1, y= -½, z= 3

=4(-1)²+[1/4(-1/2)²]+[1/9(3)²]-[2(-1)(-1/2)]+[1/3(-1/2)(3)]-[4/3(3)(-1)]

=4(1)+[1/4(1/4)]+[{1/9}(9)]-[(-2(-1/2)]

-1/2+4

=4+(1/16)+1-1-(1/2)+4

=8+(1/16)-(1/2)

=128+1-8/16

=121/16
