A:
Answer:1) the quadratic formula2) factoring (zero product property)Step-by-step explanation:1) using quadratic formula(b)² - 4ac  ----(always write the formula)3 ( 4x + 1 )² - 5 =25(12x + 1)² - 5 = 25 (using (a+b)^2)144x² + 24x +1 - 5 = 25144x²+ 24x - 4 = 25144x² + 24x =29144x² + 24x - 29= 0 (thus, formed and equation)A=144, b= 24, c= -29(24)² - 4(144 X -29)576 - 4 X -4176576 + 16704=017280>0, therefore it has 2 distinct real roots2) x²-8x+12=0sum= -8, product= 12-2,-6so,x²-2x -6x + 12x ( x - 2 ) -6 ( x - 2 )(x-2) (x-6)X= 2, 6Hope it is correct and helpful Stay safesorry for the late answer
