(4x-5)(6x+5) first foil the two out take and multiply the first two terms then the first and
last term then the last term multiplied by the first term then multiply the last two terms.
(4x)(6x) 24x^2(4x)(5)20x(-5)(6x)-30x(-5)(5)-25= 24x^2+20x-30x-25 so now combined like terms so =24x^2-10x-25 thats the final answer thats the trinomial
