3 0

Answer:

x = ±4

Step-by-step explanation:

Hi there!

$x^2-16=0$

Move 16 to the other side

$x^2=16$

Take the square root of both sides

$\sqrt{x^2}=\sqrt{16}\\x=\pm4$

I hope this helps!

Jerome tries to find the value of the expression 3 - 6 + 5 by first applying the commutative property he rewrites the expression

Lana71 [14]

Wrong in sign change

How?

In commutative law the sign doesn't change whenever it is applied.

Thus

$\\ \sf{:}\implies 3-6+5$

$\\ \sf{:}\implies 3\underline{+5-6}$

$\\ \sf{:}\implies 8-6$

$\\ \sf{:}\implies 2$

Determine the factors of x2 − 12x − 20.

FrozenT [24]

Answer:

Step-by-step explanation:

Synthetic division is one way to determine whether or not a given number is a root of the quadratic. x^2 − 12x − 20 can be rewritten as x^2 - 12x + 36 - 36 - 20, or (x - 6)^2 - 56, which does not have integer solutions:

(x - 6)^2 - 56 = 0 becomes (x - 6)^2 = 56, which works out to x - 6 = ± 2√14.

None of the possible roots suggested in this problem turns out to be an actual root.

correct response: PRIME
