✏️QUADRATIC EQUATION

Problem:

  • What is the value of a,b, and c in 2x(x-3)=15

Solution:

- Used the Standard Form Ax² + bx + c = 0, and take note, that in order to get the a, b and c the equation needs to be in its Standard Form.

  • [tex]2x(x - 3) = 15[/tex]
  • [tex]2 {x}^{2} - 6x = 15[/tex]
  • [tex]2 {x}^{2} - 6x - 15 = 15 - 15[/tex]
  • [tex]2 {x}^{2} - 6x - 15 = 0[/tex]

Therefore the answer is a = 2, b = -6, and c = -15
