Question

If we used the quadratic expression below to complete a diamond, which pair of values would go on the SIDES of the diamond?

Answer 1

GIVEN:

• Quadratic equation :— x² – 4x + 5

ANSWER:

We can use middle term factorisation method to find its roots.

So, the factors of 5 which has a addition of 4 but unfortunately there is no any factor.

So, Correct choice - [E] No solution.

Answer 2

9514 1404 393

Answer:

  e. no solution

Step-by-step explanation:

You would be looking for factors of +5 that have a sum of -4. There are none (no solution). None of the values offered in the answer choices have a product of +5.

__

The discriminant of the quadratic is (-4)² -4(1)(5) = -4, so the roots are complex.
