Question

if x² -5x+4 = 0 than x ​

Answer 1

Answer:

x= 1, 4

Step-by-step explanation:

x^(2) - 5x +4 = 0

x^(2) - 5x = -4

X^(2) -5x + 25/4 = -4 + 25/4

(x - 5/2) ^(2) = 9/4

x =

$\sqrt{9 \div 4}$

x = +/- 3/2 + 5/2

Values of x = 3/2 +5/2 = 4

or x = -3/ 2 + 5/2 = 1

Answer 2

Answer:

x =1

Step-by-step explanation:

x²-5x= 0-4

4x =4

x= 4÷4

x= 1
