Answer 1

Answer:

1) b)(x-5) (x+5)

2)d)a=c

not shure about the answer

Answer 2

Answer:

Step-by-step explanation:

1 one ans is option c

and 2 one ans is option d

2 explanation Given quadratic equation is ax2 +bx+c=0

Let α and b be the roots of the equation.

It is given that α = 1/b

Now, αβ=c/a

∴   c/a =1

Hence, c=a
