Question

x² -5x +14=0
Using
quadratic
formala
find
the answer​

Answer 1

Answer:

x^2 -5x+ 14

Splitting middle terms

X^2 -7x+2x+ 14 ( 14× X^2 = 7x× 2x )

X(X-7) -2(x-7)

(X-7)(X-2)

Answer 2

Answer:

x^2 -5x + 14 = 0

x^2 - 7x - 2x + 14 = 0

x ( x - 7 ) - 2 ( x - 7)

(x - 2) (x - 7)

quadratic formula

x =( - b + √b^2 - 4ac )/ 2a

a = 1

b = -5

c = 14

x = (-1 + √ -5^2 - 4× 1 × 14) / 2

= (-1 + 5 - 56 ) / 2

= (-1 - 51 )/ 2

= - 52 / 2

= - 26
