Simplify the expression 6x+12y+5+2y+8 what is the coefficient of y and what is the constant
frez [133]
We want to find the coeficient of the y terms when added together so find all the y terms

+12y and +2y
we add them together
12y+2y=(12+2)y=(14)y=14y
coeficient is 14


the constant is the number that is set already or the number that doesn't have it multiplied by a placeholder exg. 4 is a constnat but 4x is not so find the constants
+5 and +8
we add
5+8=13
the constant is 13


y coeficient=14
constant=14

Write a quadratic equation in standard form.
Naya [18.7K]

Answer:

  1.  x^2 +2x -24 = 0

  2.  x^2 -7x +10 = 0

Step-by-step explanation:

If you look at the factored and expanded forms of a quadratic with solutions p and q, you see ...

  (x -p)(x -q) = x^2 -(p+q) +pq

The x-term coefficient is the opposite of the sum of solutions.

The constant is the product of solutions.

This knowledge lets you write down the standard form equation with no particular effort.

1.  x^2 +2x -24 = 0

2.  x^2 -7x +10 = 0
