Step-by-step explanation:
2x - 3 = 7
this equation can represent the senario because the number (x) is doubles (multiplyed by 2), subtracted by 3 then equal to 7
then you can just solve for x
2x=10
x=5
For
ax^2+bx+c=0
discriminatn is b^2-4ac
a=4
b=12
c=9
discriinat is
12^2-4(4)(9)=
144-144
0
the discrminat is 0
