Question

How do you factor? Please Explain! 6r^2 -26r=16+8-7r

Answer 1

Combine like terms I belive

Answer 2

6r^2-19r-24=0

Answer 3

@rockindud how did you get zero?

Answer 4

Combine the like terms

Answer 5

you have 26 r and -7r

Answer 6

sorry -26r and -7r

Answer 7

You want to get rid of the numbers to the right

Answer 8

Thats what you should have right now

Answer 9

You getting this?

Answer 10

@rockindud Im not saying you're wrong btw I'm just thinking that the final equation would be 6^2 -19r = 24

Answer 11

The equation should be 6r^2 -19r - 24 =0 for factorising @mattyboyy

Answer 12

\[6\left( r^2-\frac{ 19 }{ 6 }r-4 \right)=0\]
\[6\left( r^2-\frac{ 19 }{ 6 }r+\left( \frac{ -19 }{ 12 } \right)^2-\left( \frac{ -19 }{ 12 } \right)^2-4 \right)=0\]\[6\left\{ \left( r-\frac{ 19 }{ 12 } \right)^2-\frac{ 361 }{ 144 }-4 \right\}=0\]
\[6\left\{ \left( r-\frac{ 19 }{ 12 } \right)^2-\frac{ 361+576 }{ 144 } \right\}=0\]
\[6\left\{ \left( r-\frac{ 19 }{ 12 } \right)^2-\left( \frac{ \sqrt{937} }{ 12 } \right)^2 \right\}=0\]
\[6\left( r-\frac{ 19 }{ 12 }+\frac{ \sqrt{937} }{ 12 } \right)\left( r-\frac{ 19 }{ 12 }-\frac{ \sqrt{937} }{ 12 } \right)=0\]
