Answer:
(- 3, 0) and (- 1, 0)
Step-by-step explanation:
Given
x² + 4x + 3 = 0 ← in standard form
(x + 1)x + 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
x + 3 = 0 ⇒ x = - 3
coordinates of the roots are (- 3, 0) and (- 1, 0)
Answer:
b
Step-by-step explanation:
Answer:
x = 12
Step-by-step explanation:
- Write in a different way: 2(2x + 8) = 64
- Apply the distributed property, so it now looks like this: 4x + 16 = 64
- Subtract 16 from each side, so it now looks like this: 4x = 48
- Divide each side by 4 to cancel out the 4 next to x. It should now look like this: x = 12
I hope this helps!
