B) when the coefficient of x^2 is negative

Answer:

  when the coefficient of x^2 is negative

Step-by-step explanation:

Suppose if we have a trinomial  x^2 - 5x+6

We can factor this trinomial by finding two factors whole product is +6 and add upto -5

Suppose we have a trinomial -x^2 +5x-6

Here factoring is not possible directly

so we need to factor out  negative from x^2

To factor any trinomial x^2 should be positive

So we factor out -1 when the coefficient of x^2 is negative

Brrunno [24]

Charlie has $3.15 in his bank which contains only nickels and dimes. There are 9 more nickels than dimes. Then Number of dimes =18

and Number of nickels =27

<h3>What is basic algebra ?</h3>

Mathematical expressions can be used to depict situations or issues, and algebra is the field of mathematics that does this. For a mathematical expression to have meaning, it needs to include variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division. Algebra is used in every area of mathematics, including coordinate geometry, calculus, and trigonometry. A straightforward algebraic expression is 2x + 4 = 8.

Given that : Charlie has $3.15 in his bank which contains only nickels and dimes. There are 9 more nickels than dimes

Let d be the number of dimes

d + 9 = Number of nickels

A dime = 0.1

nickle is = 0.05

0.1d + 0.05d + 0.45 = 3.15

0.15d = 2.7

d = 18

Number of dimes =18

Number of nickels = 18 + 9

=27
