What is a quadratic equation?
A quadratic equation is any equation that can be rearranged in standard form as where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0.
a+bx+c , a, b, c are integers .
formula: −b±√b2−4ac/2a
Given equation ,
2 -12x-20=0
By comparing with the quadratic equation
Here, a=2, b= -12, c= -20.
X=−b±/2a
X= -(-12) + /2(2)
X=12+- /4
X=12+- /4,
X=12+- (-4)/4
X=12+(-4)/4 and x=12-(-4)/4
X= 12-4/4 and x=12+4/4
X=8/4 and x= 16/4
X=2 and x= 4
Therefore, the square of the equation 2x2-12x-20=0 is x= 2 and x=4.
