Answer:
when a>0 then you will have a cup so up
when a<0 then you will have a cap so down
Answer:
Step-by-step explanation
In the form ax^2+bx+c
a x c should equal two factors of b
However, in this equation
1 x 19 has no factors that = 10
so you must use the Quadratic Formula which is,
x = 
so the answer should be
x = 
x = 
x =
and x = 
The opposite of left is right, so the number opposite k is k units to the right.
let the two numbers be x and y
From the first sentence,
xy=24
x+y=10
Then make y in equation 2 the subject of the formular and substitute in equation 1
x+y=10
y=10-x
substituting in equation 2
x(10-x)=24
open the bracket
10x-x^2=24
=-x^2+10x=24
Transfer the constant to the left hand side
=-x^2+10x-24=0
Then factorise completely
