Factor completely. 6x^2+3x-63

1 answer:

4 0

An alternate method would be to take out 3 first

(since it is common to each term) 3(2x + x - 21)

now break down the middle terms 3(2x - 6x + 7x - 21) now you can proceed to factoring your equation.

Find the measure of angle A. 4x 135° 5x A

Mkey [24]

<h2>Using this equation:</h2>

 $4 \times + 5 \times + 135 = 180$ 

<h2>We can solve for X:</h2>

 $9 \times + 135 = 180 \\ 9 \times = 45 \\ \times = 45$ 

<h2>Multiply this value of x to 4 and 5 to get the other two angels.</h2>

Solve for x in the equation x^2-14+31=63

Bingel [31]

To solve for a variable, you need to get it (x) by itself.

x² - 14 + 31 = 63 Add 31 to -14
x² + 17 = 63 Subtract 17 from both sides of the equation
x² = 46 Square root both sides
x = $\pm \sqrt{46}$

Check your work by plugging in $\sqrt{46}$ for x and then $- \sqrt{46}$ .

$\sqrt{46}$ ² - 14 + 31 = 63 Square $\sqrt{46}$
46 - 14 + 31 = 63 Subtract 14 from 46
32 + 31 = 63 Add
63 = 63

$- \sqrt{46}$ ² - 14 + 31 = 63 Square $- \sqrt{46}$
46 - 14 + 31 = 63 Subtract 14 from 46
32 + 31 = 63 Add
63 = 63

So, x is $\sqrt{46}$ and $- \sqrt{46}$ .
