Question

pls help me in this​

Answer 1

a. (121 - 4x²)/(2x + 11)

=> [11² - (2x)² ] / (2x + 11)

(11 - 2x) (2x + 11) / (2x + 11)

(11 - 2x) is Answer

b. (0.25a² + ab + b²)/(0.5a + b)

=> (0.25a² + (0.5×2)ab + b²) / (0.5 + b)

(0.5 + b)² / (0.5 + b)

0.5 + b is Answer

c. (4p² - m² + 2mn - n²) /(2p+ m - n)

=> [4p² - (n² - 2mn + m²)]/(2p + m - n)

[(2p)² - (n - m)²]/(2p + m - n)

[2p - (n - m) ] [2p + m + n] / (2p + m -n )

(2p - n + m)(2p + m + n) / (2p + m - n)

(2p + m + n) is Answer
