2x2 - 5x + 1 = 0
by Quadratic Formula: x = (-b+√b2-4ac)/2a
a = 2
b = -5
c = 1
x = [-(-5) +√(-5)2 - 4(2)(1)]/2 (2)
= (5 + √25 - 8)/4
= (5 + √17)/4
= (5 +4.12)/4
= 2.28

How do you solve 0 equals x squared minus ten x plus 16?
x^(2) - 10x + 16 = 0 Factors of '16', which are, 1,2,4,8,16. Select two numbers from this list that add/subtract to '10' . They are '2' and '8'. Setting up brackets ( x 2)(x 8) Since '16' is positive(+), then both signs must be the same. Since '10x' is negative (-) , then both signs are negative. Hence (x - 2)(x - 8 ) = 0 When x - 2 = 0 x = 2 & when x - 8 = 0 x = 8 So the two answers are ,2, & ,8, .
