Answer: A. x= -1 - 7
B. x= -1+ 7
Step-by-step explanation: or this equation: a=1, b=2, c=-6
1x2+2x+−6=0
Step 1: Use quadratic formula with a=1, b=2, c=-6.
x=−b±√b2−4ac/2a
x=−(2)±√(2)2−4(1)(−6)/2(1)
x=−2±√28/2
x=−1+√7 or x=−1−√7
Answer:
A
Step-by-step explanation:
Answer:
Step-by-step explanation:
We have been given an equation:
y=5x+3
The above equation is the equation of line
If we compare the given equation with general equation of line which is y=mx+c
Where. m is the slope of line.
Here on comparing we get
m=5 and c=3
To find x-intercept put y=0
Its x-intercept is (-0.6,0)
To find y-intercept put x=0
Its y-intercept is (0,3)
Answer:
D) 3x^4 + 22x^3 + 31x^2 - 6
Step-by-step explanation:
