Question

2x²-5x+2=0 solve this quadratic equation by formula meathod​

Answer 1

Answer:

X=2 ; X=1/2

Step-by-step explanation:

2x^2 -4x-x+2=0

2x(x-2)-1(x-2)

(x-2) (2x-1)

x=2 ; x=1/2

Answer 2

2x² - 5x + 2 = 0

comparing with ax²+ bx + c = 0 we get

a = 2, b = -5, c = 2

Formula: b²- 4ac = (-5)² - 4 × 2 × 2

= 25 - 16

= 9

Formula: x = [- b² - 4ac +- (root b² - 4ac] / 2a

= [- (9) +_ (root9)]/2×2

= [-9 +- 3]/4

now, x = (-9 + 3)/4 or x = (-9 - 3)/4

x = -4/4 or x = -12/4

x = -1 or x = -3

x = -1 or x = -3 is the solution for above quadratic equation,,
