+ 8x + 7 will be:​

Answer 1

Step-by-step explanation:

Correct option is

A

12

p(x)=x

2

−8x+k

a=1,b=−8,c=k

α+β=

a

−b

=8, αβ=

a

c

=k, α

=(α+β)

2

−2αβ

40=8

2

−2k

2k=24

k=12

Answer 2

Answer:

${x}^{2} + 8x + 7 = 0$

$(x + 1)(x + 7) = 0$

$x = - 1 \\ x = - 7$

that's is your answer
