Answer 2

Hey dear here is the your answer!!!!!!

________________________

⭐️ To check whether any no. is zero of any quadratic or not we put the no. in place of x and if it comes 0 then the no. is zero of polynomial ....⭐️

$= > 2 {x}^{2} + x - 1 \\ = > 2(1 \div 2) ^{2} + 1 \div 2 - 1 \\ = > 2(1 \div 4) - 1 \div 2 \\ = > + 1 \div 2 - 1 \div 2 \\ = > 0$
Therefore it is a zero ....♠️♠️♠️♠️
