Question

factrise 50b^2c^2-98a^2​

Answer 1

Taking out 2 as common factor , we get

= 2{25b²c² - 49a²}

= 2{ (5bc)² - (7a)² }

=2{(5bc+7a)(5bc-7a)} [ Since , a²-b² = (a+b)(a-b) ]

Hence , 50b²c² - 98a² = 2{(5bc - 7a)} .......

Answer 2

50b^2c^2-98a^2

Thus, according to question

Step-by-step explanation:

(a-b) ^2=a^2-2ab+b^2 2(25b^2c^2-49a^2) 2(5bc^2-7a) 2(5bc+7a)(5bc-7a)
