6x²+13x-15

Answer 1

         \(6x^2+13x-15\)

\(=6x^2+18x-5x-15\)

\(=6x.\left(x+3\right)-5.\left(x+3\right)\)

\(=\left(x+3\right).\left(6x-5\right)\)

Answer 2

\(6x^2+13x-15\)

\(=6x^2+18x-5x-15\)

\(=6x\left(x+3\right)-5\left(x+3\right)\)

\(=\left(x+3\right)\left(6x-5\right)\)

Answer 3

\(6x^2+13x-15\)

\(\Rightarrow6x^2+18x-5x-15x\)

\(\Rightarrow6x\times\left(x+3\right)-5\times\left(x+3\right)\)

\(\Rightarrow\left(x+3\right)\times\left(6x-5\right)\)
