2x^2-28=10x
x^2-14=5x
x^2-5x-14=0
(x-7)(x+2)=0
x = 7, -2

Step-by-step explanation:
ratio of baskets to tries = 5:7
if 45 baskets are made, how many tries?
5 : 7
45 : x
we cross multiply
5x = 45*7
x = 63 potential points from trials
since each try is worth 3 points, 63/3 = 21
They had 21 3-point tries
0 because 5 0 times is nothing
