Factor x² + 12x + 35

Factoring a monic quadratic means guessing two numbers which multiply together to the constant, here 35, and add up to the linear coefficient, here 12. 35 doesn't have that many factors so we quickly land on 5 and 7 as the numbers we seek:

x² + 12x + 35 = (x + 5)(x + 7)

What is the awnser to the circled equations?

Answer:

$y = - \frac{1}{3}x - 1$

Step-by-step explanation:

We have to write an equation of a line which passes through the given point (-9,2) and is perpendicular to the given straight line y = 3x - 12 ........... (1)

Now, equation (1) is in the slope-intercept form and the slope of the line is 3.

Let, m is the slope of the required line.

So, 3m = -1

{Since, the product of the slopes of two perpendicular straight lines is -1}

⇒ $m = - \frac{1}{3}$
