Question

Factorise: 32a1 -50b2​

Answer 1

Answer:

2(4a+5b)(4a-5b)

Step-by-step explanation:

2(16a² - 25b²)

2[(4a)² - (5b)²]                                                            [a² - b² = (a+b)(a-b)]

2(4a+5b)(4a-5b)                                              

Answer 2

Answer:

Step-by-step explanation:

$32a^{2} - 50b^{2} \\2(16a^{2} - 25b^{2} )\\ 2((4a)^{2}-(5b)^{2} )\\2(4a + 5b)(4a - 5b)$

Second step -  Took common factor 2

Third Step - represented in the form $a^{2} - b^{2}$

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