Given : x = 1 and y = 6 is a solution of the equation 8x - ay + a² = 0.
To find : values of a
Solution :
We have 8x - ay + a² = 0 ………(1)
On Substituting x = 1 and y = 6 in eq 1, we obtain,
⇒ 8 × (1) – a × (6) + a² = 0
⇒ 8 - 6a + a² = 0
⇒ a² - 6a + 8 = 0
⇒ a² - 4a - 2a + 8 = 0
[By middle term splitting]
⇒ a(a - 4) - 2(a - 4) = 0
⇒ (a - 2)(a - 4) = 0
⇒ a = 2, 4
Hence the values of 'a' are 2 & 4.
