mhm remember distribute last parentheses by negative one $\large\rm \color{red}{-1}(x^4y^3+x^4y^4)=\color{red}{-1}(x^4y^3) ) \color{reD}{-1} (x^4y^4)$

|dw:1434148785729:dw| it's 6y to the 3rd power you forgot 3 :-)

i made a type let me fixx that

$$\color{blue}{\text{Originally Posted by}}$$ @Nnesha mhm remember distribute last parentheses by negative one $\large\rm \color{red}{-1}(x^4y^3+x^4y^4)=\color{red}{-1}(x^4y^3) ) \color{reD}{-1} (x^4y^4)$ $$\color{blue}{\text{End of Quote}}$$ supposed to be $\large\rm \color{red}{-1}(x^4y^3+6x^4y^4)=\color{red}{-1}(x^4y^3) ) \color{reD}{-1} (6x^4y^4)$ now distribute -1 times 6x^4y^4 = -6x^4y^4 right negative times positive = negative

so would the answer be $7x ^{3}-9x ^{4}y ^{4}-11x ^{4 }y ^{3}$

yep! :-)
