Question

-1/2<x<3, then the value of 2xsquare – 5x – 3 is
d) not determined
c) negative
b) positive
a) zero​

Answer 1

Answer:

A "quadratic" is a polynomial that looks like "ax2 + bx + c", where "a", "b", and "c" are just ... Since I need my factors to sum to plus-five, then I'll be using the factors +2 and +3. It will negative❤

Answer 2

Step-by-step explanation:

Given that

2x² - 5x - 3

we know it is a quadratic equation

let us find the value of x

let

2x² -5x - 3 = 0

and also given that -1/2 is smaller than x , x is smaller than 3, then

let

i am taking x as 2 and -1

2(2)²-5(2)-3 2(-1)²-5(-1)-3

16-10-3. 2 +5-3

16-13. 7-3

=3. = 5.

here we calculated with 2 values

but we got positive

there fore answer is (b) positive

if my answer is correct plz follow me

and make me as brilliant
