Step-by-step explanation:
19.
2x^2+x-6=0
x^2+x-12=0
(x+2)(2x-3)=0
x=-2,3/2
20.
x^2+8x+15=0
(x+3)(x+5)=0
x=-3,-5
For this problem, you can use the proportion 1696/x = 32/100 since 1696 is 32% (or 32/100) of an unknown number of students .
You can cross-multiply to get 32x = 169600
Then divide on both sides by 32 and get to 5300.
