Question

find the value of The polynomial 5x - 4x^2 + 3 at x=1

Answer 1

Answer :-

• Value of given quadratic polynomial = 4

To Find :-

• The value of 5x - 4x² + 3 if x = 1

Given :-

• x = 1

• Quadratic polynomial 5x - 4x² + 3 or -4x² + 5x + 3

Step By Step Explanation :-

As given in the question we have quadratic polynomial 5x - 4x² + 3 or -4x² + 5x + 3 and we need to calculate the value of the given polynomial if x = 1.

So by substituting the value of x = 1

$\implies\sf5(1) - 4 {(1)}^{2} + 3 \\ \\\implies\sf 5 - 4 + 3 \\ \\ \implies\sf8 - 4 \\ \\\implies\sf 4$

Therefore the value of given quadratic polynomial = 4
