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.

Olivia is 5 years older than Nicole. The sum of their ages is 35. How old is each girl?
Step-by-step explanation:
how this helps!
2y + 2x = 6
2y - x = 12
Subtract
3x = -6, x = -2
2(-2) + 2y = 6
-4 + 2y = 6
2y = 10, y = 5
Final solution: x = -2, y = 5
y = 0x + 3
switch x and y and solve for y if possible
x = 0y +3
x = 3
Not a function because it doesn't pass the vertical line test .
