Which of the following are the factors of 3ab(a + b)?
Which of the following equations are correct? (i) (a+b+c)2=a2+b2+c2−2(ab+bc+ca) (ii) (a+b)3=a3+b3+3ab(a−b) (iii) (a−b)3=a3−b3−3ab(a+b) (iv) a2−b2=(a+b)(a−b)
Which of the following equation/s is/are correct? \(i) (a + b + c)^2 = a^2 + b^2 + c^2 - 2(ab + bc + ca)\) \(ii) (a + b)^3 = a^3 + b^3 + 3ab(a - b)\) \(iii) (a − b)^3 = a^3 - b^3 - 3ab(a + b)\) \(iv) a^2 - b^2 = (a + b)(a - b)\)
