Question

factories X2 - 2xy - 3y2​

Answer 1

Answer:

(x + y)(x - 3y)

Step-by-step explanation:

We can use trinomial factorisation to split the middle term

Product = -3x²y²

Sum = 2xy

x² - 2x - 3y²

= x² - 3xy + xy - 3y²

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

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

Answer 2

In the above question given data

we have factorize the above equation

we are solving in the following way consider

the given expression

The equation is$X^{2} -2xy-3y^{2}$

$X^{2} -2x-3y^{2} \\X^{2} -3xy+xy-3y^{2} \\X(x-3)+y(x-3y)\\(x+y)(x-3y)$

Hence the required factorization is

$(x+y)(x-3y)$

Note;the given equation should be

$X^{2}-2xy-3y^{2}$
