Question

Factorise 25/4xpower2 - y/q power2
​

Answer 1

Step-by-step explanation:

Use formula,

${a}^{2} - {b}^{2} = (a - b)(a + b)$

then you get your answer.

Do it by yourself. Best of Luck budd.

Answer 2

Answer: Refer to the attachment.

Algebraic Identity used: a² - b² = (a + b)(a - b)

More Identities:-

• (a + b + c)² = a² + b² + c² + 2(ab + bc + ca)
• (x + a)(x + b) = x² + (a + b)x + ab
• (a + b)³ = a³ + b³ + 3ab(a + b)
• (a - b)³ = a³ - b³ - 3ab(a - b)
• a³ + b³ + c³ - 3abc = (a + b + c)(a² + b² + c² - ab - bc - ca)
• 2(a² + b²) = (a + b)² + (a - b)²
• 4ab = (a + b)² - (a - b)²
