Question

What is the value of the coefficient of "a" when the quadratic equation y = (5x − 2)(2x + 3) is written in standard form?

−11

−6

7

10

Answer 1

There is no "a" in the equation.
Do you mean the formula:

Ax + By = C

Answer 2

yeah i guess soo.. cause thats the question.. idrk but your formula seems right

Answer 3

Okay, I think you mean the quadratic formula.

y = ax^2 + bx+ c

y = (5x - 2)(2x + 3)
y = 10x^2 + 15x - 4x - 6
y = 10x^2 + 11x - 6

Looking at that, what do you think is a?

Answer 4

so a = 10?

Answer 5

That's right! :)
