16. Solve -3x2 - 9x + 12 = 0.

AURORKA [14]

Given :

-3x² - 9x + 12 = 0

To find :-

Value of x .

Solution :-

Given equation ,

-( 3x² + 9x -12 ) = 0
3x² + 9x - 12 = 0
3x² + 12x - 3x - 12 = 0
3x ( x +4) -3( x +4) = 0
(3x -3)(x +4) = 0
x = 3/3 , -4
x = 1 , -4

PLEASE ANSWER THIS, ASAP. PLEASE, LOOK AT THE PICTURE, AND PLEASE SOLVE IT RIGHT. PLEASE.

kupik [55]

Answer:

$x=11$

Step-by-step explanation:

Angle EFB = 180 - 147 = 33 (Angles on a straight line add up to 180 degrees)

Angle FEB = 180 - 4x (Angles on a straight line add up to 180 degrees)

Since the angles in a triangle add up to 180 degrees ,

$33+(180-4x)+x=180$

Remove brackets:

$33+180-4x+x=180$

Add/Subtract:

$213-3x=180$

Subtract 213 from both sides:

$213-3x-213=180-213$

$-3x=-33$

Divide both sides by -3:

$\frac{-3x}{-3}=\frac{-33}{-3}$

$x=11$
