Find the zeros of the function g(x) = 2x2 - 5x + 2.

sertanlavr [38]

G(x) = 2x² - 5x + 2 = 2x² - 4x - x + 2 = 2x · x - 2x · 2 - 1 · x - 1 · (-2)

= 2x(x - 2) -1(x - 2) = (x - 2)(2x - 1)

g(x) = 0 ⇔ (x - 2)(2x - 1) = 0 ⇔ x - 2 = 0 or 2x - 1 = 0

x = 2 or x = 0.5

Consider the proof.

fiasKO [112]

Answer:

Correct choice is B

Step-by-step explanation:

In step 4 were proved that $\triangle ABC\sim\triangle DEC.$

By definition, similar triangles have proportional lengths of corresponding sides. To the side AB corresponds side ED, to the side AC corresponds side DC and to the side BC corresponds side EC. Thus,

$\dfrac{AC}{DC}=\dfrac{BC}{EC}.$
