Answer:
a = - 2, b = 4, c = - 3
Step-by-step explanation:
The standard form of a quadratic equation is
ax² + bx + c = 0 ( a ≠ 0 )
Compare - 2x² + 4x - 3 = 0 to the standard, giving
See below in bold.
-2x^2 + 4x - 3 = 0 Compare this with the standard form:
ax^2 + bx + c = 0
We see that a = -2, b = 4 and c = -3.
step 3
he should have subtracted 9 to the outside.
whatever you do to the inside you must do to the opposite to the outside
so your final form must be -7(x-3)^2 + 8
