Question

(a+2d)(a+6d)=8 solve it​

Answer 1

Hey mate!!

Here's ur answer:

Simplifying

(a + 6d)(a + 8d) = 8

Multiply (a + 6d) * (a + 8d)

(a(a + 8d) + 6d * (a + 8d)) = 8

((a * a + 8d * a) + 6d * (a + 8d)) = 8

Reorder the terms:

((8ad + a2) + 6d * (a + 8d)) = 8

((8ad + a2) + 6d * (a + 8d)) = 8

(8ad + a2 + (a * 6d + 8d * 6d)) = 8

(8ad + a2 + (6ad + 48d2)) = 8

Reorder the terms:

(8ad + 6ad + a2 + 48d2) = 8

Combine like terms: 8ad + 6ad = 14ad

(14ad + a2 + 48d2) = 8

Solving

14ad + a2 + 48d2 = 8

Solving for variable 'a'.

Reorder the terms:

-8 + 14ad + a2 + 48d2 = 8 + -8

Combine like terms: 8 + -8 = 0

-8 + 14ad + a2 + 48d2 = 0

The solution to this equation could not be determined.
