Mathematics: Factor the following standard form trinomials in x*2 + bx + c form. First look for the number pairs that multiply to c (sign included). Second, see which of those pairs ALSO adds up to b [sign included]. Third, use those numbers to write the factored form in (x + r) (x + s) form. *work please*

Step-by-step explanation:

$e)\ x^2+4x-12,\ ab=-12,\ a+b=4,\ a,b=6,-2,\ (x+6)(x-2)\\ \\ f)\ x^2-9x+20,\ ab=20,\ a+b=-9,\ a,b=-4,-5,\ (x-4)(x-5)\\ \\ g)\ 3x^2-21x+30,\ 3(x^2-7x+10)\ a,b=-2,-5,\ 3(x-2)(x-5)\\ \\ h)\ 20x^3-40x^2-60x,\ 20x(x^2-2x-3),\ a,b=-3,1,\ 20x(x-3)(x+1)$
