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:
- 9x²-12x = -5, standard form: 9x²-12x+5=0 ⇒a=9, b= -12, c=5
- 3x² + 7 = -8x, standard form: 3x²+8x+7=0 ⇒a=3, b= 8, c=7
- 4x² = -10 x, standard form: 4x² +10 x=0 ⇒a=4, b= 10
Quiz
- 4x²-13x = 7, standard form: 4x²-13x - 7=0 ⇒a=4, b= -13, c=-7
- 3x² + 7 = -8x + 5, standard form: 3x² +8x + 2 ⇒a=3, b= 8, c=2
- 4x ² = - 10x + = X+6 (i think this question is not complete)
