The expression x^4 + 4 can be factorized as Watch Solution
If 3x = a + b + c, then the value of (x – a)^3 + (x – b)^3 + (x – c)^3 – 3(x – a)(x – b)(x – c) is Watch Solution
If (x + y)^3 – (x – y)^3 – 6y(x^2 – y^2) = ky^3, then k = Watch Solution
If x^3 – 3x^2 + 3x – 7 = (x + 1)(ax^2 + bx + c), then a + b + c = Watch Solution
If x/y + y/x = -1 (x, y ≠ 0), then the value of x^3 – y^3 is Watch Solution
Which of the following is a factor of (x + y)^3 – (x^3 + y^3) ? Watch Solution
Each of the following questions contains STATEMENT-1 (Assertion) and STATEMENT-2 (Reason) and has following four choices (a), (b), (c) and (d), only one of which is the correct answer. Mark the correct choice. (a) Statement-1 is true, Statement-2 is true; Statement-2 is a correct explanation for Statement-1. (b) Statement-1 is true, Statement-2 is true; Statement-2 is not a correct explanation for Statement-1. (c) Statement-1 is true, Statement-2 is false. (d) Statement-1 is false, Statement-2 is true. Statement-1 (Assertion): (a – b)^3 + (b – c)^3 + (c – a)^3 = 3(a – b)(b – c) (c – a) Statement-2 (Reason): If a + b + c = 0, then a^3 + b^3 + c^3 = 3abc Watch Solution
Statement-1 (Assertion): If 3x = a + b + c, then Statement-2 (Reason): (x – a)^3 + (x – b)^3 + (x – c)^3 = 3(x – a)(x – b)(x – c) If a + b + c = 0, then a^3 + b^3 + c^3 = 3abc Watch Solution
Statement-1 (Assertion): If a + b + c = 5 and ab + bc + ca = 10, then a^3 + b^3 + c^3 – 3abc Statement-2 (Reason): a^3 + b^3 + c^3 – 3abc = (a + b + c) {(a + b + c)^2 – 3(ab + bc + ca)} Watch Solution
Statement-1 (Assertion): If a, b, c are all non-zero such that a + b + c = 0, then a^2/bc + b^2/ca + c^2/ab = 3 Statement-2 (Reason): If a + b + c = 9 and a^2 + b^2 + c^2 = 35, then ab + bc + ca = 23 Watch Solution
Statement-1 (Assertion): The value of {(0.027)^3 + (0.023)^3}/ {(0.027)^2 – (0.027)×(0.023) + (0.023)^2} is 0.05 Statement-2 (Reason): a^3 – b^3 = (a – b) (a^2 – ab + b^2) Watch Solution
