Question

Which factorizations can be used to identify the real zones of the function f (x) = -20x^2 + 23x-6

Answer 1

-2 (10x^2 +23×3)
the aswers is: -2 (10x^2 + 69)

Answer 2

For this case we have the following function:
f (x) = -20x ^ 2 + 23x-6
We can rewrite the function.
For this, we factor.
We have then:
f (x) = - (5x-2) (4x-3)
Therefore, the real solutions are:
x1 = 2/5
x2 = 3/4
Answer:
f (x) = - (5x-2) (4x-3)
x1 = 2/5
x2 = 3/4
