Question

7. Find the zero of the polynomial 2x²+7x-4​

Answer 1

Step-by-step explanation:

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

It is given that

p(x) = 2x² + 7x -4

So we get

2x² + 7x -4 = 0

By splitting the middle term

2x (x + 4) - 1 (x + 4) = 0

(x + 4) (2x - 1) = 0

We get

x = -4 and x = 1/2
