Hello,
I've been asked to sort this out and tbh I haven't a scooby... not done algebra since I was a school...
Create an expression when expanded the coefficient is equal to constant terms...
(x+a) (x+b)
any ideas?
Cheers

(x+a) (x+b)
It would be like this: x^2+ax+bx+ab

Think of it like that, with the thicker lines noting the things you have to multiply |

Both are the same, just in different order. |

Sorry that's my bad, should have arranged them in the same order as Tranced to avoid confusion, both are 100% correct though |

I had a teacher which used to say that that method was the happy face method.
I just put all the variable first and then the constant.
