Exercise #1

Create an algebraic expression based on the following parameters:

a=1,b=1,c=1 a=-1,b=-1,c=-1

Video Solution

Step-by-Step Solution

The goal is to express the quadratic equation y=ax2+bx+c y = ax^2 + bx + c using the given parameters a=1 a = -1 , b=1 b = -1 , and c=1 c = -1 .

First, substitute the values of a a , b b , and c c into the standard form:

  • Substituting a=1 a = -1 , the term becomes x2 -x^2 .

  • Substituting c=1 c = -1 , the term remains 1-1.

Combine these terms to form the full expression:


y=x2x1 y = -x^2 - x - 1

Therefore, the algebraic expression for the parameters a=1 a = -1 , b=1 b = -1 , and c=1 c = -1 is: x2x1 -x^2 - x - 1 .

Video Solution

Step-by-Step Solution

To solve this problem, we'll start by substituting the given parameters into the standard quadratic formula:

y=ax2+bx+c y = ax^2 + bx + c

The problem gives us the values:

  • a=1 a = -1
  • b=8 b = -8
  • c=0 c = 0

This means we need to replace a a , b b , and c c in the formula:

y=(1)x2+(8)x+0 y = (-1)x^2 + (-8)x + 0

Simplifying this expression further:

  • The term with a a : (-1)x^2\) results in x2 -x^2 .
  • The term with b b : (-8)x\) simplifies to 8x -8x .
  • The term with c c : 0 0 contributes nothing to the expression, so it is omitted.

Thus, the final algebraic expression is:

y=x28x y = -x^2 - 8x

Therefore, the algebraic expression based on the given parameters is

x28x -x^2 - 8x .

Answer

x28x -x^2-8x
