Question

m²-3m+mn-3n
Help me with the question

Answer 1

Factorise

${m}^{2} - 3m + mn - 3n \\ = m(m - 3) + n(m - 3) \\ = (m + n)(m - 3)$

Answer 2

Answer:

$x = \frac{b + - \sqrt{b {}^{2} } - 4ac }{2a} \\ \frac{3 + - \sqrt{1 + 3 \times 1 \times 1} }{2} \\ = \frac{3 + - \sqrt{4} }{2} \\ = x = \frac{5}{2} \\ x = \frac{1}{2}$
