WebFeb 18, 2024 · The general form of a cubic equation is, ax 3 + bx 2 + cx + d = 0. So, the required equation is, P (x) = 6x 3 + (–5)x 2 + 0x + 2 = 6x 3 – 5x 2 + 2 Question 2. Find a cubic equation in y for the values of a, b, c and d as 2, –3, 1, 5 respectively. Solution: We have, a = 2, b = –3, c = 1 and d = 5 WebExample 5. Solve the cubic equation x 3 – 6 x 2 + 11x – 6 = 0. Solution. To solve this problem using division method, take any factor of the constant 6; let x = 2. Divide the polynomial by x-2 to. (x 2 – 4x + 3) = 0. Now solve the quadratic equation (x 2 – 4x + 3) = 0 to get x= 1 or x = 3.

WebSimplify the following by cubing: 1. (x + 5y) 3 + (x – 5y) 3 Solution: We know, (a + b) 3 = a 3 + 3a 2 b + 3ab 2 + b 3 and, (a – b) 3 = a 3 – 3a 2 b + 3ab 2 – b 3 Here, a = x and b = 5y Now using the formulas for cube of two binomials we get, = x 3 + 3.x 2 .5y + 3.x.
