Answer:
factorisation method
4x² - 3x + 9 = 2x + 1
4x² - 3x-2x +9-1 = 0
4x² - 5x + 8 = 0
sum = -5
product= 4x8
32
factors=(try to look for the numbers when added they give -5 a!d when multiplied they give 32
press the numbers in the position of -5
factorise
each blacket equal it to 0
and solve for the two values of x
Add the two trips together for total Km’s:
4500 + 11700 = 16,200 km.
divide total km by speed:
16,200 / 1,100 = 14.727272 hours
0.727272 x 60 minutes per hour = 43.636363 minutes, round up to 44 minutes
total time: 14 hours and 44 minutes
