Question

15ab(a2-7a+10) divide 3b(a-2) factorise the expression and divide the form of directed​

Answer 1

first you will factories it and then divide it

Answer 2

$\frac{15ab〚 {a}^{2} - 7a + 10 〛}{3b(a - 2)} \\ =\frac{ \cancel{ 3b} \times 5a〚 {a}^{2} - 7a + 10 〛}{ \cancel{ 3b}(a - 2)} \\ = \frac{5a〚 {a}^{2} - 7a + 10〛}{a - 2} \\ = \frac{5a〚 {a}^{2} - 5a - 2a + 10 〛}{a - 2} \\ = \frac{5a〚a(a - 5) - 2(a - 5) 〛}{a - 2} \\ = \frac{5a〚(a - 5)( \cancel{ a - 2}) 〛}{ \cancel{ a - 2}} \\ = \underline{ \underline{ 5a(a - 5)}}$
