x=2a−b±b2−4ac
Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

Step-by-step explanation:
Answer:
There are 6 * 6 = 36 total outcomes from throwing 2 dice. Of those, there is only 1 that will give you a sum less than 3 (1 + 1) so the answer is 1 / 36.
Replace x and y with the given values and solve the equations:
A) 3(5) + 2 = 17
B) 2(5)^2 = 50
C) (5-2)^2 = 9
Given.
(1)
(2)
Re-arrange equation (2)
Multiply equation (2) by -1
(3)
Combine like terms and solve.
Divide by (2y) and solve for (y).
Substitute (y) for equation (1).
Add (8) to both sides.
Divide by (3).
Check your work.
