me algebraic expression eka hadanna dannawada

(3𝑥 + 1)(2𝑥 + 5𝑦) − (𝑦 − 1)(7𝑥 − 𝑦)

 

[imhotep]

In general if you expand (a+b)(c+d) = ac+bc+ad+bd

Use the above to expand the first expression, then expand the second - keeping in mind the negative sign, which applies to the whole expanded result.

=6x2 +15xy+2x+5y-(7xy-y2-7x+y)
=6x^2 +15xy+2x+5y-7xy+y^2+7x-y
=6x^2 +8xy+9x+4y+y^2
