Question

10)
The zero of the polynomial f(x) = 2x+7 is​

Answer 1

To find the zero of a polynomial we just equate the polynomial to zero

So

Let f (x) = 0

But f (x) = 2x + 7

So

$2x + 7 = 0$

$2x = - 7$

$x = \frac{ - 7}{2}$

So x = - 7/2 is the required zero

Answer 2

Answer:

2x+7=0

2x=-7

x=-7/2

this is the correct answer
