Question

When solving the equation –3a2 = 7a – 3 using the quadratic formula, what values should be used for a, b, and c?
Question 7 options:



a = –3, b = 7, and c = –3



a = –3, b = –7, and c = 3



a = 3, b = 7, and c = 3



a = 3, b = –7, and c = –3

Answer 1

Answer:

a = -3, b = -7 and c = 3

Step-by-step explanation:

–3a2 = 7a – 3 must be re-written in standard form:

–3a2 - 7a + 3 = 0

Then a = -3, b = -7 and c = 3 (third answer choice)

Answer 2

Answer:

a = -3, b = -7, and c = 3

Step-by-step explanation:

–3a² = 7a – 3

-3a² - 7a + 3 = 0

a = -3, b = -7, c = 3
