Question

.please answer correctly​

Answer 1

Answer:

a =2

Step-by-step explanation:

p(m)=m²-am+7

p(-1)=(-1)²-a×(-1)+7

= 1+a+7

=8+a

but p(-1)=10(given)

= 8+a=10

= a=10-8

=a=2

Answer 2

$\boxed{a = 2}$

$\sf \:Answer$

Given that : If the value of the polynomial

$\longmapsto\sf {m}^{2} - am + 7 \: \\\sf where\: m =- 1 \: gives \: the \: solution \:10$

Now , put the value of m in the equation and put the equation equal to 10 , we'll get the value of a , here we go

$\sf( - 1) {}^{2} - a( - 1) + 7 = 10 \\ \sf1 + a + 7 = 10 \\ \sf a + 8 = 10 \\ \sf \: a = 10 - 8 \: = 2$

Therefore , the value of a is 2 .
