Question

How would you write 2x^2-7=11 in both quadratic property and square root property?

Answer 1

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.
