Question

factorise 56x^2y^2-14x^2
write correct answer and show it's process ​

Answer 1

Answer:

56x²y²-14x²=14x²(2y+1)(2y-1)

Step-by-step explanation:

Given that:-

56x²y²-14x²

=>(4×14)x²y²-(14×1)x²

Taking 14x² as common

=>14x²(4y²-1)

=>14x²[(2y)²-1²]

=>14x²(2y+1)(2y-1)

(since (a+b)(a-b)=a²-b²))

56x²y²-14x²=14x²(2y+1)(2y-1)
