Question
how do I solve this question?
Factorize: 51y^2 - 2580y - 39879
Please help if possible, thank you.
i'm going to show you the easiest way to be able to factor anything that deals with parabolas.
Quadratic Formula
y = (-b ± sqrt(b^2 - 4ac))/(2a)
but first reduce your problem into
3(17y^2 - 860y - 13293)
y = (-(-860) ± sqrt((-860)^2 - 4(17)(-13293)))/(2(17))
y = (860 ± sqrt(1643524))/34
y = (860 ± 1282)/34
y = 2142/34 or -422/34
y = 63 or (-211/17)
in factored form, your answer would be
3(17y + 211)(y - 63)
