Question

find the value of polynomial 2x²+5x+1+ at x=3 explain step by step

Answer 1

Given:-

• $2x²+5x+1$

To Find:-

• the value of polynomial 2x²+5x+1+ at x=3

Solution:-

Let

$p(x) = 2x²+5x+1$

Now, Putting the value of x=3 in p(x).

$p(3) = 2 \times {3}^{2} + 5 \times 3 + 1$

$= > p(3) = 2 \times 9 + 15 + 1$

$= > 18 + 16$

$= > 34$

Answer 2

Given:-

2x²+5x+12x²+5x+1

To Find:-

the value of polynomial 2x²+5x+1+ at x=3

Solution:-

Let

p(x) = 2x²+5x+1p(x)=2x²+5x+1

Now, Putting the value of x=3 in p(x).

p(3) = 2 \times {3}^{2} + 5 \times 3 + 1p(3)=2×3

2

+5×3+1

= > p(3) = 2 \times 9 + 15 + 1=>p(3)=2×9+15+1

= > 18 + 16=>18+16

= > 34=>34
