factor (m+n)^2-(m+n)+9

factor

(m + n)^{2} - (m + n) + 9

m^{2} + 2 mn + n^{2} - m - n + 9

Solution steps

(m + n)^{2} - (m + n) + 9

(m + n)^{2} : m^{2} + 2 mn + n^{2}

= m^{2} + 2 mn + n^{2} - (m + n) + 9

- (m + n) : - m - n

= m^{2} + 2 mn + n^{2} - m - n + 9

a x^{2} + b x^{2} - a y^{2} - b y^{2}

3^{4}

x^{2} + x z + x y + yz

m^{2} + mn + m q + n q

[- 9.5]
