x=17-3

x=14

y-2=38

y=38+2

What is the factored expression of 63x^2-3x-6

Murljashka [212]

Answer:

$3(3x-1)(7x +2)$

Step-by-step explanation:

$63x^2-3x-6$

Suppose a generic quadratic equation

$ax^2 + bx + c$

To factor this equation, I need to find its roots. Then we use the quadratic formula of:

$\frac{-b + \sqrt{b^2-4ac}}{2a}$

and

$\frac{-b + \sqrt{b^2-4ac}}{2a}$

So, for the equation 63x ^ 2-3x-6 we have:

$\frac{3 + \sqrt{(-3)^2-4(63)(-6)}}{2(63)} = \frac{1}{3}$

and

$\frac{3 - \sqrt{(-3)^2-4(63)(-6)}}{2(63)} = \frac{-2}{7}$

So:

$(x-\frac{1}{3}) = 0\\\\(3x-1) = 0$

and

$(x - (-\frac{2}{7})) = 0\\\\(x+ \frac{2}{7}) = 0\\\\(7x +2) = 0$

Finally the polynomial is:

$(3x-1)(7x +2)$

Through:(-1, -2), slope = 5

kherson [118]

Answer:

y=5x+3

Step-by-step explanation:

Hi there!

We're given the point (-1, -2) and a slope of 5. We need to find the equation of the line in slope intercept form.

Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

Since we're already given the slope, we can substitute that immediately into the equation

here it is so far:

y=5x+b

now we need to solve for b

Since the line will pass through the point (-1,-2), we can use it to solve for b

substitute -1 as x and -2 as y into the equation

-2=5(-1)+b

multiply

-2=-5+b

add 5 to both sides

3=b

substitute that into the equation

therefore, the equation of the line is <u>y=5x+3</u>

Hope this helps! :)
