What is the factored form of the expression? d^2 = 36d + 324

(x-43.45)(x+7.45)=0.

Step-by-step explanation:

We have the quadratic equation i.e.

Now, the roots of the quadratic equation are given by

So, from the given equation, we have,

a = 1, b =-36 , c = -324.

Substituting the values in , we get,

i.e.

i.e.

i.e.

i.e.  and i.e.

i.e.  and i.e.

i.e. x = 43.45 and x = -7.45

Hence, the factored form of the given expression will be (x-43.45)(x+7.45)=0.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
