Answer:
(6-√21, 6+√21)
Step-by-step explanation:
x^2 - 12x = -15
(x - 6)^2 - 36 = -15
(x - 6)^2 = 21
x - 6 = ± √21
x = 6 ± √21
Rewrite the parabola in standard form and use this formula to find the vertex (h,k).
= (2,-1)
You’ll need 10 teaspoons because 6 x 2 is 12, so 5 x 2 is 10
Answer:
y=x-2
Step-by-step explanation:
If you have drawn the graph of .
To determine the equation of the line which should be drawn to solve the equation: x² - 4x +3=0
Simply carry out the subtraction:
The equation of the line which should be drawn is: y=x-2
What this means is simply:
If
