Question

10x^2+7x-3

Answer 1

how do you factorise this?

Answer 2

do u need a solution or u need to know to make factors?

Answer 3

\[10x^2+7x-3\] Firstly, multiply 10 and -3. That gets you -30. Then, think to yourself; which numbers add up to 7 but multiply to make -30? If it helps, write all the multiples of -30 out, eg:
30 x -1
15 x -2
10 x -3
6 x -5
So, which one of these adds up to make 7? That would be 10 and -3. So: \[10x^2+10x-3x-3\] Then, you "make" brackets.\[10x(x +1)-3(x+1)\] From this, you can get:\[(10x-3)(x+1)\] which is the beginning equation factorised.
