i'll show you how to do the 1st one

2x^2 +13x +15
-multiply the "x^2" coefficient and the constant....2*15 = 30
-Find 2 factors of 30 which add up to 13 .... 10+3 = 13 , 10*3 = 30
so i will use 10 and 3 , Note: if nothing works here then the expression cannot be factored
-Next, rewrite expression replacing 13x with 10x+3x
-group terms together
(2x^2 +10x) +(3x +15)
factor each group

2x(x+5) +3(x+5)
factor out the (x+5)
--> (x+5)(2x+3)
done
