2x^2-6x-20=0 value of a

a = 2

Step-by-step explanation:

The equation 2x² - 6x - 20 = 0 is in standard form for a quadratic formula.

The general equation for standard form is: y = ax² + bx + c

Sometimes we make "y" => 0 when we are finding the roots (x-intercepts).

Notice "a" is attached to x² in the standard form.

In your question, the number attached to x² is 2.

∴ a = 2

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
