Question

4x2-5x+3,when x is 3

Answer 1

$\textbf{Answer :}$

Let us take

f (x) = 4x² - 5x + 3

When, x = 3,

f (3) = 4 (3)² - 5 (3) + 3

= 4 (9) - 15 + 3

= 36 - 12

= 24

Answer 2

Solution :

Given : 

Equation : 4x² - 5x + 3

Value of x = 3

Proof : 

Substituting the value of " x " in the equation we get,

= 4 ( 3 )² - 5 ( 3 ) + 3 

= 4 × 9 - 15 + 3

= 36 - 12

= 24

Hence the value of equation is 4.
