U1 Quadratics
Different forms of quadratics
Vertex form
a(x-h)^2+k
vertex=h&k
expand to get standard form, usually vertex form could be converted by using the completing the square method
Standard form
ax^2+bx+c
Factored form
a(x-q)(x-p)
x-intercept=q&p
expand to get standard form and then to vertex form.
could transfer standard form by using the cross method and factoring the terms
Solving quadratics
Methods

Standard
vertex
Factored
get the x intercepts directly from the vale of p and q
