Question

Solve question number 16

Answer 1

Step-by-step explanation:

Given Equation is a²x² - 3abx + 2b² = 0

⇒ a²x² - 2abx - abx + 2b² = 0

⇒ ax(ax - 2b) - b(ax - 2b) = 0

⇒ (ax - b)(ax - 2b) = 0

⇒ x = (b/a), x = (2b/a)

Hope it helps!

Answer 2

a²x²-3abx+2b²

= a²x²-2abx+b²+b²-abx

= (ax-b)²-b(ax-b)

= (ax-b)(ax-b) - b(ax-b)

= (ax-b)(ax-b-b)

= (ax-b)(ax-2b)
