You can get this by finding the vertex at -b/2a for x value and plugging in to find the y value.
Answer: 17
Step-by-step explanation:
y= 1
(3y + 2)(7y)
(3(1) + 2(7(1)) Replace y with given number
(3 + 2(7)) Multiply 1 to 3 and 7
(3 + 14) Multiply 2 and 7
(17) Add 3 and 14
How to solve them? Just move over the variables to one side and solve for them until you have just the variable, whilst doing the same actions to the side with only numbers. For parentheses with a coefficient, use distributive method.
