Question

when the value of the polynomial 3 x^2-5x+4 at :X = (-1)​

Answer 1

The value of polynomial $3x^{2}-5x+4$ at x = -1 is 12.

Step-by-step explanation:

The polynomial is:

$3x^{2}-5x+4$

Compute the value of the polynomial at x = -1 as follows:

$3x^{2}-5x+4=3(-1)^{2}-5(-1)+4$

                    $=3+5+4\\=12$

Thus, the value of polynomial $3x^{2}-5x+4$ at x = -1 is 12.

$\sf{The\:value\:of\:the\:polynomial\:is\:12!}$

$\mathfrak{Step\:By\:Step\:Explanation}$

Let us substitute the value of x in the given polynomial.

• 3x² - 5x+ 4

⤐ 3 ( -1 )² - 5( -1 ) + 4

⤐ 3 + 5 + 4

⤐ 12.

So the value of the polynomial is 12.
