Question

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

Answer 1

just multiply the binomials then compare it with standard form u'll get the answer

Answer 2

alright i multiplied it and i got 10x^2+11x-6 so if you compare it with ax^2+bx+c then u'll get the answer

Answer 3

\[y=5x(2x)+5x(3)-2(2x)-2(3)\]
\[y=10x^2+15x-4x-6\]
\[y=10x^2+11x-6\]
a = 10
b = 11
c=-6

Answer 4
