Which of the following represents the factorization of the trinomial below?<br>x2 - 6x +9

valentinak56 [21]

For this case we must factor the following expression:

$x ^ 2-6x + 9$

We must find two numbers that, when multiplied, result in 9 and when added, result in -6.

These numbers are -3 and -3.

$-3-3 = -6\\-3 * -3 = + 9$

Then, the factored expression is of the form:

$(x-3) (x-3) = (x-3) ^ 2$

Thus, the correct option is option C.

Is the answer B or C

klio [65]

We will calculate it like this, We will make a right angle triangle by adding one new point called O for example, and O is located right under the point C, and on the right side of point D, so the coordinated for this point are O (8, -2). From there, length CD is calculated using the Pythagorean theorem, because we know that the CO = 4 and DO = 4, so:

CD^2 = CO^2 + DO^2

CD^2 = 4^2 + 4^2

DC^2 = 16 + 16

DC^2 = 32

DC = square root of 32 = square root of 16 * square root of 2

DC = 4 * square root of 2

The correct answer is B. 4*square root of 2.
