The general form of a quadratic equation is
ax2 + bx + c = 0
ax2 - bx + c = 0
ax2 + bx - c = 0
ax2 - bx - c = 0
The general form of a quadratic equation is ax2 + bx + c = 0.
The value of x which satisfies the quadratic equation is called
Root of the equation
Zero of the equation
Solution of the equation
All of these
The value of x which satisfies the quadratic equation is called the root\zero\solution of the equation.
Find the roots of the quadratic equation x² + 2x - 8 = 0.
x = −4, x = 2
x = −4, x = −2
x = 4, x = −2
x = 4, x = 2
x² + 2x - 8 = 0
x² + 4x − 2x - 8 = 0
(x + 4)(x − 2) = 0
Find the roots of the quadratic equation x² − 12x + 36 = 0.
x = −6, x = 6
x = −6, x = −6
x = 6, x = −3
x = 6, x = 6
x² − 12x + 36 = 0 x² − 6x − 6x + 36 = 0 (x − 6)(x − 6) = 0 x = 6, 6
