Question

x square + 12 x minus 1333 is equal to zero

Answer 1

Hey mate !!

Here's the answer !!

This question can be solved using simple factorisation method known as splitting the middle term method.

x² + 12x - 1333 = 0

We can write 1333 in the form of 43 * 31. And if we subtract 31 from 43 we get,

x² + 43x - 31x -1333 = 0

Taking common roots, we get,

x ( x + 43 ) - 31 ( x + 43 ) = 0

( x + 43 ) ( x -31 ) = 0

=> x = 31, - 43

Hope my answer helps !!

Cheers !!

Answer 2

Heya mate !!

here is your answer :-

_________________________

● Your ques :- x^2 + 12x - 1333 = 0
_________________________

:- Splitting middle term , we get

==> x^2 + 43x - 31x - 1333 = 0

:- On taking common ,

==> x ( x + 43 ) - 31 ( x + 43 )

==> ( x - 31 ) ( x + 43 )

:- So , we get ,

● x = 31 and

● x = - 43
