Question

2. Fill in the blanks with the correct demonstrative pronouns: a) Waiter I'm sorry to say it but cake you have just served me is not fresh.​

Answer 1

Answer:

Comparing f(x) = 4x2 - 8kx - 9 with ax2+bx+c we get

a=4; b=-8k and c=-9.

Since one root is the negative of the other, let us assume that the roots are p an -p.

Sum of the roots, a+(-a)=-b/a= - (-8k) / 4

0=2k

k=0
