Question

last question please help Part 1: Create your own quadratic equation that cannot be solved by factoring, but can be solved using the quadratic formula. Identify the values of a, b, and c, and find the solutions using the quadratic formula. Show all work to receive credit.

Part 2: Using complete sentences, explain how you know that the equation from Part 1 cannot be solved by factoring, but can be solved by using the quadratic formula.

Answer 1

please help ?

Answer 2

\[\bf y = x^2 + a\]Where 'a' is any constant would give you a quadratic that can't be normally factored and would require the use of the quadratic formula.

@msellier

Answer 3

Note that \(\bf a>0\).

Answer 4

thats it ? @genius12 ??

Answer 5

@msellier That's just an example of the many quadratic equations that can't normally be factored. If you have any quadratic in the form \(\bf x^2+a\) such that \(\bf a>0\), it can never be normally factored. You can come up with many more different quadratic equations not in this form that can't be normaly factored

Answer 6

ok thank you sorry but could you explain me how to do this as well ?
Identify the solutions of 3x^2 − x − 4 = 0.

x = −1 over 3, x = 4

x = 1 over 3, x = −4

x = 4 over 3, x = −1

x = −4 over 3, x = 1

Answer 7

@genius12 ?

Answer 8

Basically you have to find 2 numbers that multiply to -12 and add up to -1. Can you find 2 such numbers?

Answer 9

@msellier ??

Answer 10

?

Answer 11

@msellier Did you find the 2 numbers?
