Answer 2

$\Huge\mathfrak\orange{answer:}$

$\bf{To~subtract:}$

$\sf{~~~~~~3x^{2}-2x+5xy-7~~from~~8-8xy+3x^{2}-5x}$

$\sf{:→(8-8xy+3x^{2}-5x)-(3x^{2}-2x+5xy-7)}$

$\sf{:→8-8xy+3x^{2}-5x-3x^{2}+2x-5xy+7}$

$\bf{Collecting~the~like~terms,~we~get:}$

$\sf{~~~~~~(8+7)+(-8xy-5xy)+(3x^{2}-3x^{2})+(-5x+2x)}$

$\sf{:→15-13xy+0-3x}$

$\sf{:→{\orange{\underline{\boxed{\bf 15-3xy-3x}}}}}$
