Hello manjuscaria2007!


\huge \boxed{\mathbb{QUESTION} \downarrow}

3x² - 5x + 6 . Solve if value of x is (-1).


\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}


3 {x}^(2) - 5x + 6

Firstly, substitute the value of x as -1 in the equation. The equation becomes...


3( - 1)^(2) - 5( - 1) + 6

Now, solve it..


3( - 1) ^(2) - 5( - 1) + 6 \\ = 3 * 1 - 5 * - 1 + 6 \\ = 3 + 5 + 6 \\ = 8 + 6 \\ = \large\boxed{\boxed{ 14}}

Hope it'll help you!
