Answer:
multiply by 3, applying the multiplication property of equality
-6/5x = 4y +6
Step-by-step explanation:
Your video probably tells you what is expected here.
Ordinarily, we would multiply both sides of the equation by the least common denominator of the fraction: 15. That would eliminate <em>all</em> of the fractions. Your form seems to indicate that the coefficient of x remains a fraction after the multiplication. That makes the intent unclear to those of us who have not seen your video.
The multiplication property of equality is applied.
<h3>1.</h3>Multiply both sides of the equation by 15. This clears all the fractions.
__
<h3>2.</h3>If we just clear the fraction for y, we do that by multiplying both sides by 3.
Answer:
P(x) = - 7x² + 12
Step-by-step explanation:
Given zeros x = 2, x = - 2, x = , x = -
Then the factors are (x - 2), (x + 2), (x - ), (x +
)
and the polynomial is the product of the factors, that is
P(x) = (x - 2)(x + 2)(x - )(x +
) ← expand in pairs using FOIL
= (x² - 4)(x² - 3) ← distribute
= - 3x² - 4x² + 12 ← collect like terms
= - 7x² + 12
