Question

What is the b^2 - 4ac of x^2-5x+4=0​

Answer 1

9

Step-by-step explanation:

Given parameters:

what is b² - 4ac of

Equation x² - 5x + 4 = 0

Solution:

x² - 5x + 4 in the form ax + bx + c = 0

a is the coefficient of x² = 1

b = -5

c = 4

Input the parameters and solve;

b² - 4ac = -5² - 4(1)(4)

= 25 - 16

= 9
