Question 814163
12x^2 - 23x + 8 = -2
12x^2 - 23x + 10 = 0
find factors of 120 which add up to -23
First Number	Second Number	Sum
1	120	1+120=121
2	60	2+60=62
3	40	3+40=43
4	30	4+30=34
5	24	5+24=29
6	20	6+20=26
8	15	8+15=23
10	12	10+12=22
-1	-120	-1+(-120)=-121
-2	-60	-2+(-60)=-62
-3	-40	-3+(-40)=-43
-4	-30	-4+(-30)=-34
-5	-24	-5+(-24)=-29
-6	-20	-6+(-20)=-26
-8	-15	-8+(-15)=-23
-10	-12	-10+(-12)=-22

-8 and -15
12x^2-8x-15x+10=0
4x*(3x-2)-5*(3x-2)=0
(4x-5)*(3x-2)=0
4x-5=0
4x=5
x=5/4
3x-2=0
3x=2
x = 2/3

(2/3,5/4)
