Select the correct answer from each drop down menu

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 9 + 12x + 4x^2

1. ∠1 is complementary to ∠2 and ∠3 is complementary to ∠2. subtraction property of equality 2. m∠1 + m∠2 = 90 and m∠3 + m∠2 = 90 substitution 3. m∠1 + m∠2 = m∠3 + m∠2 definition of complementary 4. m∠1 = m∠3 given
