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
