QUADRATIC FORMULA
Practice 1.
Solve for w.
4x + x2 - 5 = 0
1) Write the equation in standard form, ax2 + bx + c = 0
4x2 + x2 - 5 = 0
x2 + 4x - 5 = 0
2) List the values for a, b, and c.
3) Plug a, b, and c into the quadratic formula.
4) Simplify the equation using the order of operations, PEMDAS, or using a calculator (or Desmos Scientific Calculator online).
