Answer:

1)


\tt 5x - 15x^2 (x^2=xx)


\tt 5x-15xx

let's rewrite 5x → 5×1, n' 15→ 5×3


\tt 5* \:1* \:x-5* \:3xx

Factor out common term(5x)


\boxed{\tt 5x\left(1-3x\right)}

2)


\tt 3x-9

Rewrite 9 → 3×3


\tt 3x-3* \:3

Factor out common term (3)


\boxed{\tt 3\left(x-3\right)}

Hope it helps! :)

Answer:

1) 5x(1 - 3x)

2) 3(x - 3)

Explanation:

Question # 1:

= 5x - 15x²

Take 5x common

= 5x(1 - 3x)

Question # 2:

= 3x - 9

Take 3 common

= 3(x - 3)


\rule[225]{225}{2}

Hope this helped!
