4 = a (0+1)(0-2)
\(\color{#0cbb34}{\text{End of Quote}}\)
4 = a * 1 * -2
Florisalreadytaken:
so
4 = a * -2
jnlkmnjkm:
2 times -2 is negative 4 but thats my only guess
Florisalreadytaken:
no -- you divide it
Florisalreadytaken:
a = 4/-2

we get
y = -2 (x+1)(x-2)
jnlkmnjkm:
now simplify
jnlkmnjkm:
-2 + 1?
Florisalreadytaken:
what? no
Florisalreadytaken:
what we would get is
-2x^2 + 2x + 4
