Answer:
x= -5-
/4, - 5+/4
Step-by-step explanation:
solve the equation for x by finding a,b, and c of the quadratic then applying the quadratic formula (the full thing under "answer:" is the exact answer
Answer:
a = 4 and b = - 30
Step-by-step explanation:
Expand the left side and compare like terms on both sides, that is
(x + 2)(x - 3)(x + 5) ← expand the first pair of factors using FOIL
= (x² - x - 6)(x + 5) ← distribute
= x³ + 5x² - x² - 5x - 6x - 30 ← collect like terms
= x³ + 4x² - 11x - 30
Compare like terms with x³ +ax² - 11x + b
4x² and ax² ⇒ a = 4
+ b and - 30 ⇒ b = - 30
Answer:
um... what are trying to say?
Step-by-step explanation:
Make the same denominator then Add which would be 4/12 + 1/12 which is 5/12
