Answer:
Step-by-step explanation:
hello :
15r² – 6r – 3 = -2r
15r² – 6r – 3 +2r =0
15r²-4r -3 =0
delta =b² -4ac a=15 b=-4 c=-3
delta =(-4)² - 4(15)(-3)=196 = 14²
r1 = (-b - √delta ) /2a = (4-14)/30 = -10/30 = -2/6 = -1/3
r2 = (-b + √delta ) /2a = (4+14)/30 = 18/30 = 3/5
Answer:
y = 4
Step-by-step explanation:
y + 6 = 5(2 - 4)
y + 6 = 10 - 20
y + 6 = 10
y + 6 - 6 = 10 - 6
y = 10 - 6
y = 4
Answer:
-2
Step-by-step explanation:
