Answer:
2a^2 + 3a - 1 ,
Step-by-step explanation:
I am assuming you mean
2a^3-a^2-7a+2
By long division:
a - 2 ) 2a^3 - a^2 - 7a + 2 ( 2a^2 + 3a - 1 <------- Quotient
2a^3 - 4a^2
3a^2 - 7a
3a^2 - 6a
-a + 2
-a + 2
. . . . .
4(-9*x)
Multiply the two numbers
-36x
Final answer: -36x
They are both isosceles triangles
Equation for this line is y = -2x + (-4)
<u>Step-by-step explanation:</u>
Step 1:
Slope intercept equation for a line is of the form y= mx + b, where m is the slope and b is the y-intercept.
Step 2:
Calculate slope of the given line.
⇒ m = (y2 - y1)/(x2 - x1) = (2 - (-2))/(-3 - (-1)
⇒ m = 4/-2 = -2
Step 3:
Find y-intercept
⇒ b = - 4
Step 4:
Substitute values to get equation
⇒ y = -x -4 or y = - (x + 4)
