Question

if A=(x-y) B=(x+y) C = (x+y-z) then what is 1.A×B 2.A+B × (C)
please explain this I need to submit tomorrow

I will mark you as brainliest also​

Answer 1

Step-by-step explanation:

A=(x-y) B=(x+y) C = (x+y-z)

1. A×B

(x-y) × (x+y)

x² - xy + xy + y²

2. (A+B) × (C)

{ (x-y) + (x+y) } × (x+y-z)

2x × (x+y-z)

2x² + 2xy + 2xz

Answer 2

Ans 01:-

A*B=X2+XY-YX-Y2

=X2-Y2 (: XY-XY CANCEL OUT)

Ans 02:-

A+B*C=(x-y) +(x+y) *(x+y-z)

=(x+x-y+y) *(x+y-z)

=(2x) *(x+y-z) (-y+y cancel out)

=2x*x+2x*y-2x*z

= 2X2+2xy-2xz

final Ans
