Question

14. The zero of f(X)=2x+1=..........
​

Answer 1

$\star\:\:\bf\large\underline\blue{Question:-}$

• Find the zeros of $f(x) = 2x + 1$

$\star\:\:\bf\large\underline\blue{Solution:-}$

$f(x) = 2x + 1$

$2x + 1 = 0$

$\implies 2x = - 1$

$\implies x = \frac{ - 1}{2}$

$\implies x = - 0.5$

$\star\:\:\bf\large\underline\blue{Answer:-}$

• The value of x is -0.5

Answer 2

Answer:

(X +½)

Step-by-step explanation:

Because x+½=-½,

then,

$f(x) = 2x + 1 = 0$

$f( \frac{ - 1}{2} ) = 2 \times \frac{ - 1}{ 2 } + 1 = 0$

$f( \frac{ - 1}{2} ) = - 1 + 1 = 0$

$f( \frac{ - 1}{2} ) = 0 = 0$

Therefore, f(x)=—½ is the zero of the polynomial f(x)=2x+1.....
