Answer:
p = 3
q = -6
Step-by-step explanation:
Work backwards from the roots:
x =
3x = 2
3x - 2 = 0
Other root:
x = -3
x + 3 = 0
Multiply them together:
(3x - 2)(x + 3) = 0
3x² - 9x + 2x - 6 = 0
3x² - 7x - 6 = 0
p = 3
q = -6

Answer:
y =
Step-by-step explanation:
given y varies as the square of x then the equation relating them is
y = kx² ← k is the constant of variation
to find k use the given condition y = 25 when x = 3
k = =
⇒ y = x²
when x = 2
y = × 4 =
