Answer:
Quadratic Property 2x^2-18=0
Square Root Property x=√9 or x=+3 or x=-3
Step-by-step explanation:
Quadratic Property or a quadratic Function is of the form ax^2+bx+c=0. So our task is to equate the given expression to zero. We can equate the expression to zero by subtracting 11 on both the sides. In doing so, we get 2x^2-18=0. This is the quadratic Property of the given Expression.
Square property is finding the value for x. we have make x equal to some value. Since we already have the quadratic Property as 2x^2-18=0, we can use this to find the value of x.
so, 2x^2=18
or x^2=18/2=9
or x=√9= +3 or -3.
