Answer:
The quadratic equation is X^2 -26X +144=0
Step-by-step explanation:
You can do it shortly by using the formula
X^2-(sum)x+ product
which will give you
X^2- (8+18)x+8×18
=X^2 -26x +144
=X^2 -8x-18x + 144
=(X^2-8x)(-18x+144)
=X(X-8)-18(x-8)=0
(X-18)(X-8)=0
X-18=0 And X-8=0
X=18 X=8
. Therefore the quadratic equation is X^2 -26X +144
Subtract the cost of tickets from the total. 4x7.5=30. 58-30=28. Eight boxes of candy were purchased in total. Use c to represent candy. 8c=28. Finally, divide both by 8. 28/8= 3.5. The answer is $3.50.
