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
