Q. 3 G4.8( 5 Votes )

# Let’s find G.C.D of the following algebraic expression:x2 + xy,xz + yz, x2 + 2xy + y2

Factors of x2 + xy=x(x + y)

Factors of xz + yz=z(x + y)

Factors of x2 + 2xy + y2=(x + y)2 … (from properties of (a + b)2)

GCD is the greatest common divisor, which is equal to the product of all the common divisors.

the GCD of x2 + xy,xz + yz, x2 + 2xy + y2 is (x + y)
