Activity Change the given equations to standard form and identify the values of a,b,&c

Equations
9x²-12x = -5
2.3x² + 7 = -8x
3.4x² = -10 x

Quiz
1.4x²-13x = 7
2.3x² + 7 = -8x + 5
3.4x ² = - 10x + = X+6​

QUADRATIC EQUATION

A quadratic equation is an equation with a variable to the second power as its highest power term.

The Standard Form of a Quadratic Equation:

ax²+bx+c=0

where:

  • x represents an unknown (variable).
  • a, b, and c represent known numbers, where a ≠ 0.

The Answer to The Given Questions Above:

  1. 9x²-12x = -5, standard form: 9x²-12x+5=0 ⇒a=9, b= -12, c=5
  2. 3x² + 7 = -8x, standard form: 3x²+8x+7=0 ⇒a=3, b= 8, c=7
  3. 4x² = -10 x, standard form: 4x² +10 x=0 ⇒a=4, b= 10

Quiz

  1. 4x²-13x = 7, standard form: 4x²-13x - 7=0 ⇒a=4, b= -13, c=-7
  2. 3x² + 7 = -8x + 5, standard form: 3x² +8x + 2 ⇒a=3, b= 8, c=2
  3. 4x ² = - 10x + = X+6​ (i think this question is not complete)
