Answer:
x = 1, x = 3
Step-by-step explanation:
x² - 4x + 3 = 0
consider the factors of the constant term (+ 3) which sum to give the coefficient of the x- term (- 4)
the factors are - 1 and - 3 , since
- 1 × - 3 = + 3 and - 1 - 3 = - 4 , then
(x - 1)(x - 3) = 0 ← in factored form
equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 3 = 0 ⇒ x = 3
x2−4x+3=0
For this equation: a=1, b=-4, c=3
1x2+−4x+3=0
Step 1: Use quadratic formula with a=1, b=-4, c=3.
x=
−b±√b2−4ac

5 15
Step-by-step explanation:
since they gave the point (0,0) and slope 3
y=mx+b
0=3(0)+b
b=0
y=3x and then substitute
The value do you mean absolute value if you do it would be 4
