Therefore, (x - y)³ + (y - z)³ + (z - x)³ = 3(x - y)(y - z)(z - x) Try This: Without finding the cubes, factorise (2x - 3y)³ + (3y - 4z)³ + (4z - 2x)³ ☛ Also Check: NCERT Solutions for Class 9 Maths Chapter 2 Verified by Toppr. x3 +y3 +z3 −3xyz = (x+y+z)(x2 +y2 +z2 −xy−yz−zx) First take L.H.S. (x+y+z)(x2 +y2 +z2 −xy−yz−zx) To multiply two polynomials, we multiply each monomial of one polynomial (with its sign) by each monomial (with its sign) of the other polynomial.

X Y Z 3 Class 9Answer. Verified. 416.1k + views. Hint:We can write the term (x − y − z)3 ( x − y − z) 3 as (x −(y + z))3 ( x − ( y + z)) 3. Then, we can use the formula (a − b)3 = (a3 −b3) − 3ab(a − b).

x = z (Alternate interior angles). (1) It is given that y: z = 3: 7. Let the common ratio between y and z be a. ∴ y = 3a and z = 7a. Also, x + y = 180º (Co-interior angles on the same side of the transversal) z + y = 180º [Using equation (1)] 7a + 3a = 180º. 10a = 180º. a = 18º. ∴ x = 7a = 7 × 18º = 126º Bright Campa ALL THIS MONEY EXTENDED Samples Genius Kyle Richh What You On Wasted Samples Genius
