Assuming you are given a standard form equation, you should convert it to vertex format. If you are given root equation form, you would have to convert to standard form.
Assuming you have;
ax²+bx+c=y
a(x²+b/ax)+c=y
a(x²+b/ax+(b/2a)²-(b/2a)²)+c=y
a(x²+b/ax+(b/2a)²)+c-a(b/2a)²=y
a(x+b/2a)²+c-a(b/2a)²=y
Try to use this format to solve the problems.
Hope I helped :)
But I’m sure that I can do
Answer:
A
Step-by-step explanation:
The area of a rectangle is the product of its dimensions, that is
A = (2x - 5)(3x + 3) ← expand using FOIL
= 6x² + 6x - 15x - 15 ← collect like terms
= 6x² - 9x - 15 → A
