Question

factorise by splitting the middle term x square - 3xy - 88y square​

Answer 1

${x}^{2} + 3xy - 88 {y}^{2} \\ = {x}^{2} + 11xy - 8xy - 88y {}^{2} \\ = x(x + 11y) - 8y(x + 11y) \\ = (x - 8y)(x + 11y)$

Answer 2

Step-by-step explanation:

x ^{2} - 3xy - 88y

=.

x ^{2} - 11xy + 8xy - 88y

=

(x - 11y)(x + 8y)

is the homogeneous solution
