Split the middle term for a quadratic equations
If an equation is x^2-15x-6750 can you please simplify the split the middle term method. Because forming factors that will result in the addition as 15x is difficult for me

We can solve the equation x^2-15x-6750 = 0 by splitting the middle terms using factors of the last term (-6750) into it's factors which would add up to 15. two such factors of 6705 are (-90) + (75).
hence we can write the above equation as: x^2-90x + 75x - 6750 = 0
=> x(x-90)+75(x-90) = 0
Hence the roots of the equation are -90 and 75.
I hope this helps.
