HELP ME!!! ITS DUE TOMMOROW!! Find the largest value of $r$ such that $6r^2+7r+8=6$.
Alex787 [66]
First you need to see that this is a quadratic. I need.to put all of the values on one side of equation to see what I got.
6r^2 + 7r + 8 = 6
6r^2 + 7r + 2 = 0

Now this one is difficult to factor so i will use quadratic equation:
[-b (+-) sqrt (b^2 - 4ac)] / (2a)

we know that a b and c are in a quadratic at these positions.
ax^2 + bx + c

so
[-7 (+-) sqrt (7^2 -(4)(6)(2)] / (2) (6)
[-7 (+-) sqrt (49 - 48)] / 12
[-7 (+-) 1] /12

split into the + and - for 2 answers
(-7 + 1) / 12
-6/12
-1/2

And
(-7 -1) /12
-8 / 12
-2/3

those are.the 2 answers

But but it says largest so -1/2

The property applied is the associative property

<h3>Algebraic properties</h3>

There are several algebraic properties in mathematics; each of which have their own applications

Some of these properties are:

  • Commutative
  • Distributive
  • Associative
  • Identity

The mathematical expression is given as:

13 \cdot (20 \cdot 5)

And it is calculated as follows:

13 \cdot (20 \cdot 5) = 13 \cdot 100

13 \cdot (20 \cdot 5) = 13 00

The property applied above is the associative property
