Write the quadratic equation whose roots are 3 and -6, and whose leading coefficient is 3.
(use the letter x to represent the variable.)

Step-by-step explanation:

if the roots are 3 and -6, we can start with:

But the leading coefficient must be 3, we just add a 3 to one of the x's:

But now we have to make sure the roots work again:

So our equation is:

step-by-step explanation:

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
