Question

If p(x)= 2+5x then p(2) + p(-2) - p(1)​

Answer 1

Step-by-step explanation:

p(2) = 2+ 5*2 = 2+10 = 12

p(-2) = 2+ 5(-2) = 2-10 = -8

p(1) = 2+ 5*1 = 2+5 = 7

p(2) +p(-2) -p(1) = 12-8-7

= -3

ANSWER = -3

Answer 2

${\bold {\huge {\pink{\mathcal {ANSWER :}}}}}$

$given\\ p(x) = 2 + 5x$

$p(2) = 2 + 5 \times 2 \\ = 2 + 10 \\ p(2)= 12 - - - (1)$

$p( - 2) = 2 + 5( - 2) \\ = 2 - 10 \\ p( - 2)= - 8 - - - - (2)$

now according to the given comdition

$p(2) + p( - 2) - p(1)$

$p(1) = 2 + 5 \times 1 \\ = 7 - - (3)$

so by equation 1, 2 and 3

we get

$= 12 + ( - 8) - 7 \\ = 12 - 15 \\ = - 3$

so the answer will be -3
