Exercise #10

Create an algebraic expression based on the following parameters:


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

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:
