|20| = 20
= -20+5
Apply absolute rule: |a| = a, a >/ 0

Find the zeros of f(x) = 4x 2 + 5x - 21.

Goryan [66]

To find the roots, you must set the function equal to zero and then solve for x.
For f(x)=4x^2 + 5x -21
The zeros of the function are: x=-3, x=7/4

Solve the equation for the given variable k/3-11=-20

taurus [48]

$\frac{k}{3-11}$ = - 20

You can subtract the numbers in the parenthesis:
(3-11) = (-8)

Multiply the denominator to both sides so it cancels out and isolates the variable $\frac{k}{-8}$ × -8 = - 20 × -8
-8 and -8 cancels out

k = 160

Quick check:
$\frac{160}{(3-11)}$ = -20
$\frac{160}{-8}$ = - 20
- 20 = - 20
Yes its right

the answer is: k =160
