Answer:

B

Step-by-step explanation:

Using the rules of exponents

(a^m)^{n} = a^{mn}

a^{-m} = \frac{1}{m}

Then

(y^b)^{4} = \frac{1}{y^{24} }

y^{4b} = y^{-24}

Equate the exponents

4b = - 24 ( divide both sides by 4 )

b = - 6 → C

Find constants p and q such that x^4-2x^3-x^2+2x+10=(x^2+px+5)(x^2+qx+2)
likoan [24]

Answer:

p = -4 q = 2

Step-by-step explanation:

  1. Expand the brackets ( yes the entire thing).
  2. group together the values with same co-effiecients; like (q+p)x^3 etc etc.
  3. equate the co-effiecients on the left hand side to the now grouped ones on the right, for example [x^3]: -2x^3= (q+p)x^3, the x^3 cancels and ull get an equation only in terms of p and q. do the same for [x] and ull get an equation with only q, solve this and get the value for q [q = 2].
  4. sub in this value for the [x^3] equation and ull get an answer for p [p= -4].

hope my explanation is understandable lol
