Answer:
Step-by-step explanation:
y=3(x+1)²
note : y ≥ 0 because : 3(x+1)² ≥ 0
calculate x : (x+1)² = y/3
x + 1 = √(y/3) or x + 1 = - √(y/3)
x = -1 + √(y/3) or x = - 1 - √(y/3)
Answer:
x = 10 and x = 2
Step-by-step explanation:
x² - 6x + 20 = 6x
x² - 12x + 20 = 0
We should have values of p and q that multiply and give the answer as 20 and if added give -12.
=> p * q = -10 * -2 = 20
=> p + q = -10 + (-2) = -12
Therefore, we can factor it now:
(x - 10) (x - 2) = 0
We can say:
x - 10 = 0, and x - 2 = 0
=> x = 0 + 10, and x = 0 + 2
=> <u>x = 10 and x = 2</u>
