Question

p(x) = x2 - x + 3, then p 7√7= ?​

Answer 1

Answer:

346-7√7

Step-by-step explanation:

p(x) = x^2-x+3

p(7√7) = (7√7)^2 - 7√7 + 3

=343 -7√7 + 3

= 346 - 7√7

Answer 2

Given :

• p(x) = x2 - x + 3

To find :

• p (7√7)

Solution :

To find p (7√7) put x = 7√7 in p(x) = x2 - x + 3.

$\implies \: p(x) = {x}^{2} - x + 3$

$\implies \: p(7 \sqrt{7} ) = {(7 \sqrt{7}) }^{2} - 7 \sqrt{7} + 3$

$\implies \: p(7 \sqrt{7} ) = (49 \times 7) - 7 \sqrt{7} + 3$

$\implies \: p(7 \sqrt{7} ) = 343 - 7 \sqrt{7} + 3$

$\implies \: p(7 \sqrt{7} ) = 343 + 3- 7 \sqrt{7}$

$\implies \: p(7 \sqrt{7} ) =346 - 7 \sqrt{7}$

Answer :

$346 - 7 \sqrt{7}$
