Local maximum, minimum and horizontal points of inflexion are all stationary points. We learn how to find stationary points as well as determine their natire, maximum, minimum or horizontal point of inflexion. The tangent to the curve is horizontal at a …
Find the value of k for which the quadratic equationkx2 14x +8=0
Webx2-2x-8. Find the Zeros of each of the following quadratic polynomials and verify the relationship between the zeros and their coefficients. WebCorrect Answer - Option 2 : – 4 ≤ k ≤ 4 Given: kx2 – 8x + k Concept Used: ax2– bx + c = 0 has real liner factors when, b2 – 4ac = 0 Calculation: Comparing the given equation with ax2 + bx + c = 0, We get a = k, b = 8, and c = k ⇒ (8)2 – 4(k)(k) = 0 ⇒ 64 – 4k2 = 0 ⇒ 4k2 = 64 ⇒ k2 = 16 ⇒ k = √16 ⇒ k = +/– 4 ∴ The value of k is – 4 ≤ k ≤ + 4. ezxa
