Question

FACTORISE THE FOLLOWING :-

х² – 6xy – 7у²​

Answer 1

Answer:

x

$x { }^{2} - 6xy - 7y ^{2}$

$x ^{2} - 7xy \times 1xy - 7y {}^{2}$

$x(x - 7y) - 1y(x - 7y)$

$(x - 1y)(x - 7y)$

Step-by-step explanation:

Love thesa type questions.............

Answer 2

Step-by-step explanation:

x² - 7xy + xy - 7y²

=> x(x - 7y) + y(x - 7y)

=> (x + y)(x - 7y)
