Which factorizations can be used to identify the real zeros of the function f(x)=-20x squared +23x-6?

Mama L [17]

The first thing we will do is rewrite the function.
We have then:
f (x) = - 20x ^ 2 + 23x-6
We now look for the zeros of the function:
-20x ^ 2 + 23x-6 = 0
- (4x-3) (5x-2) = 0
Answer:
The factorization that can be used to find the zeros of the function is:
- (4x-3) (5x-2) = 0

How do you solve X + x/7 + (x +x/7 ) = 60?

kozerog [31]

$x+ \frac{x}{7} +(x+ \frac{x}{7} )=60$

Remove parentheses (a)= a

$x+ \frac{x}{7} +x+ \frac{x}{7}$

Group like terms:

$x+ \frac{x}{7} +x+x$

Add similar elements:

$\frac{x}{7} + \frac{x}{7} =2 \frac{x}{7}$

$= 2 \frac{x}{7} +x+x$

Add similar elements:

$x+x = 2x$

$2 \frac{x}{7} +2x$

Multiply $2 \frac{x}{7}$

$= \frac{2x}{7} +2x$

$\frac{2x}{7} +2x = 60$

Multiply both sides by 7 :

$\frac{2x}{7} *7+2x*7 = 60*7$

$16x = 420$

$x = 420 / 16$

$x = \frac{105}{4}$

hope this helps!
