Question

1. Verify that is -1/2 is zero of p(x)=2x+1​

Answer 1

$\large\bf\underline\red{Answer \: :-}$

We have,

p(x) = 2x + 1 and -1/2 is the zero.

Verification :-

$\sf\longrightarrow{p(x) = 2 \bigg( \frac{ - 1}{2} \bigg) + 1 = 0 } \\ \\ \sf\longrightarrow{p(x) = \frac{ - 2}{2} + 1 = 0} \: \: \: \: \: \: \: \: \\ \\ \sf\longrightarrow{p(x) = - 1 + 1 = 0} \: \: \: \: \: \: \: \: \\ \\ \bf\longrightarrow \red{p(x) = 0 = 0} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

Hence Verified
