Question

Find the value of the polynomial
5x-4x² +3 at
x=2
x=1​

Answer 1

Answer:

-3, 4

Step-by-step explanation:

Let x=2,

5(2)-4(2)^2+3

10-16+3

-3

Let x=1,

5(1)-4(1)^2+3

5-4+3

4

Answer 2

Answer:

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

At x=2

$= 5 \times 2 - 4 \times {2}^{2} + 3$

$= 10 - 16 + 3$

$= - 3$

At x=1

$= 5 \times 1 - 4 \times {1}^{2} + 3$

$= 5 - 4 + 3$

$= 4$
