Answer:
d= 4 or 5.66
Step-by-step explanation:
(-2,7) and (2,3)
d =
d=
d =
d= 4 or 5.66
First you plug in the variables:
(-3)(2)+(6)(-3)(4)
Multiply:
-6+(-18)(4)
-6+-72
Add and your answer comes out to be:
-78
Answer:
Step-by-step explanation:
Combine like terms in 2x^2-5x+1=x+4: 2x^2 -6x - 3 = 0
The coefficients of this quadratic are {2, -6, -3}. Apply the quadratic formula. Start by finding the discriminant, b^2 - 4ac:
b^2 - 4ac = (-6)^2 - 4(2)(-3) = 36 + 24 = 60
Because the discriminant (60) is positive, we know that this quadratic has two real, unequal roots:
-(-6) ± √60 6 ± (√4)(√15)
x = -------------------- = ----------------------
2(2) 4
or:
6 ± 2√15 3 ± √15
x = ----------------- = ----------------
