Please use " ^ " to indicate exponentiation: x^2 + 3x - 4 = 0
Here, a = 1, b = 3 and c = -4.
The formula for the discriminant is b^2 - 4(a)(c).
Substituting the given values of a, b and c, we get:
(3)^2 - 4(1)(-4)
Evaluating this, we get 9 + 16 = 25.
The discriminant is 25.
-3 plus or minus √25
Taking this further, x = ------------------------------------
2
-3 plus or minus 5
or: x = -------------------------------- => {-4, 1} (solutions)

4+5=9 divided by 3 is 3 times 4 is 12. so it's 12
hope this helps;)
39.50-23.76-2.57-1.49=11.68
take the sales and subtract the expenses
1-m
2-y
3-e
should be the answers to the question
They need to be number C plus 3-2:7
