Question

5. Multiply and verify the result by taking x = 1, y = -2.

(3x - y) (3x + y)
(ii) (x - 2xy + y) (x - 1)
(iii) (x + y - 2xy) (x - 4y + xy)
please solve point no 3​

Answer 1

Answer:

The first x is the horizontal coodinate (abscisa) and second is the vertical coordinate (ordenate). Both are coordinates. (x,y) has the meaning of a complex number: x is the real part and y is the imaginary part: x+yi. (x,y) has the meaning of a plane's vector from origin of coordinates.Aug

Answer 2

Answer:

27

Step-by-step explanation:

X=1

Y=-2

(iii)(x+y-2xy)(x-4y+xy)

=>{1-2-2(1)(-2)} {1-4(-2)+(1)(-2)}

=>{1-2+4} {1+8-2}

=>{5-2} {9-2}

=>{3}{7}

=>27
