What are the factors of the equation when it’s in factored form? 2a^2 + 8a - 15 = 3a - 3
1 answer:
Answer:
(2a+3 ) (a-4 )=0
Step-by-step explanation:
2a^2 + 8a - 15 = 3a - 3
Subtract 3a from each side
2a^2 + 8a-3a - 15 = 3a-3a - 3
2a^2 + 5a - 15 = - 3
Add 3 to each side
2a^2 + 5a - 15+3 = 3 - 3
2a^2 -5a -12=0
(2a+3 ) (a-4 )=0 These are the factors

Answer:
8. -385°, 335°
9. -30°, 330°
Step-by-step explanation:
8. θ = -25°
-25-360 = -385°
-25+360 = 335°
9. θ = -390°
-390+360 = -30°
-30+360 = 330°
