Question 7 Given that one of the zeroes of the cubic polynomial ax3 + bx2 + cx + d is zero, the product of the other two zeroes is: (A) βˆ’ c/a (b) c/a (c) 0 (d) βˆ’π‘/a Let p(x) = ax3 + bx2 + cx + d Given that one zero is 0 ∴ 𝜢 = 0, and we need to find product of other other two zeroes, i.e. 𝜷𝜸 We know that Sum of product of Zeroes = 𝑐/π‘Ž 𝜢𝜷 + 𝜷𝜸 + 𝜢𝜸 = 𝑐/π‘Ž 0 Γ— 𝛽 + 𝛽𝛾 + 0 Γ— 𝛾 = 𝑐/π‘Ž 𝜷𝜸 = 𝒄/𝒂 So, the correct answer is (B)
