find value of n, 3n² - n - 1430 = 0
Answers
Answer:
(n-22).(3n+65)
Step-by-step explanation:
(3n²-n)-1430
-4290 + 1 = -4289 -2145 + 2 = -2143 -1430 + 3 = -1427 -858 + 5 = -853 -715 + 6 = -709 -429 + 10 = -419 -390 + 11 = -379 -330 + 13 = -317 -286 + 15 = -271 -195 + 22 = -173 -165 + 26 = -139 -143 + 30 = -113 -130 + 33 = -97 -110 + 39 = -71 -78 + 55 = -23 -66 + 65 = -1
3n2 - 66n + 65n - 1430
3n • (n-22)
65 • (n-22)
