Question

Write the quadratic function in standard form.
1. y=(x+1)(x+2)
2. y=-2(x+4)(x-3)

Answer 1

Right now the functions are in factored form. When you combine them(my teacher calls it FOIL), you get the standard form: #1 \[x ^{2}+3x+2\]

Answer 2

OH! so basically u foil them.

Answer 3

yes

Answer 4

second: \[2x ^{2}+2x-24\]

Answer 5
