Answer:
-6, -6
Step-by-step explanation:
Given :
Solving :
- This is of the form : <u>a² + 2ab + b²</u>
- Hence, the factored form is <u>y = (x + 6)²</u>
- y = (x + 6)(x + 6)
- x + 6 = 0 ⇒ x = -6
- x + 6 = 0 ⇒ x = -6
The zeros are : -6, -6
Answer:
-x-15
Step-by-step explanation:
x-2x-15
1x-2x-15 (if a term doesn't have a coefficient then the coefficient is 1)
(1-2)x-15 (collect like terms by subtracting their coefficients)
-1x-15
-x-15 (when the term has a coefficient of -1, the number doesn't have to be written but the sign remains)
