Answer 1

Answer:

The zeroes of the polynomial is -4 and 1/2.

step by step explanation:

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(x+4)−1(x+4)=0

⇒(2x−1)(x+4)=0

⇒x= 1/2, -4

The zeroes of the polynomial 2x²+7x-4 are -4 and 1/2.
