factorise 1)m square-8m-33 please give me answer I will give like you and I will follow you and I will make you branilist​

Answer 1

Answer:

4.646

Step-by-step explanation:

Answer 2

Answer:

Need to factorise {4m}^{2} - 9mn - 9n4m

2

−9mn−9n

Solution:

Try to find common factors:

\begin{gathered}4 {m}^{2} - 9mn - 9n = 0 \\ \implies \: 4 {m}^{2} - 12mn + 3mn - 9 \end{gathered}

4m

2

−9mn−9n=0

⟹4m

2

−12mn+3mn−9

\implies \: 4m(m - 3n) + 3n(m - 3n)⟹4m(m−3n)+3n(m−3n)

\red{\bold{\boxed{\implies \: (4m + 3n)(m - 3n)}}}

⟹(4m+3n)(m−3n)

How to find the factors?

With the quadratic equation in the form:

\purple{\bold{P {(variable)}^{2} + Q(variable) + R}}P(variable)

2

+Q(variable)+R

Where P, Q and R are constants.
