Given y = (2x + 3)^2, choose the standard form of the given quadratic equation.

(2x+3)^2

=(2x+3)(2x+3)

=(2x)(2x)+(2x)(3)+(3)(2x)+(3)(3)

=4x^2+6x+6x+9

=4x^2+12x+9

D, 0 = 4x2 + 12x + 9

a=4

b=12

c=9

u what ?

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
