6 янв. 2022 г. · One of the zeroes of the polynomial 2x² + 7x -4 is a. 2 b. 1/2 c. -1/2 d. -2. Solution: We know that. Zero of the polynomial p(x) = 0.

The correct option is B 12. Let p(x)=2x2+7x−4 =2x2+8x–x–4 [By splitting middle term] =2x(x+4)−1(x+4) =(2x–1)(x+4) For zeroes of p(x), put p(x)=0.

To find the zero of 2x2+7x−4 is same as solving the equation 2x2+7x−4=0 ⇒2x2+8x−x−4=0 ⇒2x(x+4)−1(x+4)=0 ⇒(2x−1)(x+4)=0. ⇒(2x−1)=0,(x+4)=0

17 дек. 2021 г. · One of the zeroes of the polynomial is - 1 2. Explanation: Let p (x) = 2x 2 + 7x – 4 = 2x 2 + 8x – x – 4.
