Question

factorise given perfect square algebraic expression: 25 m+30 m+9​

Answer 1

Answer:

25m2 + 30 m + 9 = (5m)2 + (5m)(3) + (3)2 =

= (5m + 3)(5m + 3)

∴ 25m2 - 30m + 9 =

= (5m + 3)(5m + 3)

M=5/3,5/3

Step-by-step explanation:

hope u have been understood thanku

Answer 2

The Factorise of the following expression is: (5m + 3)².

Explanation for the answer:

• Common factors are the factors which are common to two or more numbers.
• It is a number with which a set of two or more numbers will be divided exactly.
• Factorising 25m²+ 30m + 9
• 25m² + 30m + 9
• 25m² + 30m + 9= (5m)²– 2 × 5m × 3 + 3²
• 25m² + 30m + 9= (5m)²– 2 × 5m × 3 + 3²Using identity (x + y)² = x² + 2xy + y²
• 25m² + 30m + 9= (5m)²– 2 × 5m × 3 + 3²Using identity (x + y)² = x² + 2xy + y²25m²+ 30m + 9 = (5m + 3)²
