Question

factorise 3x^2 + xy + 14y^2​

Answer 1

Answer:

(x+2y)(3x-7y)

Step-by-step explanation:

=3x^2+6xy-7xy-14y^2

(splitting the middle term to get the product of the 2 ends no. and that the sum is equal to the middle term)

=3x(x+2y)-7y(x+2y)

(taking out common)

=(3x-7y)(x+2y)

final answer..
