Answer:

Algebra is a branch of mathematics that substitutes letters for numbers. Algebra is about finding the unknown or putting real-life variables into equations and then solving them. Algebra can include real and complex numbers, matrices, and vectors.

An equation is a mathematical sentence that has two equal sides separated by an equal sign. 4 + 6 = 10 is an example of an equation. ... For example, 12 is the coefficient in the equation 12n = 24. A variable is a letter that represents an unknown number.

This is a very challenging equation but I'll try my best!

<span>y-k=a(x-h)^2
$Vertex(1,1) ----\ \textgreater \ y-1=a(x-1)^2 
contains~ the ~point (0,-3) 

----\ \textgreater \ 1-1=a(0-,-3)^2 

----\ \textgreater \ 1=-2a 

----\ \textgreater \ a=1/-2

Equation: Y-1=1/-2(x-2)^2$
