To simplify x^2-3 =5x

You would first subtract 5x from both sides

X^3-5x-3

Next you would plug this into the quadratic equation:

X=5+/- the square root of: -5^2 -4(1)(-3)/2(1)

Then simplify,
5+/- the squareroot of 24 + 12 / 2

5+/- The squareroot of 36 /2

5+/- 6 / 2

Then solve if it’s an addition or subtract

5+6/2

X=11/2 or 5 1/2

5-6/2

X= -1/2

The answer is x=-1/2 or x=11/2

Hope this helps

Find equation to the given value of the curve x=t^5+1, y=t^6+t, and t=-1. please help I keep getting y=-1.4x and it is incorrect

irakobra [83]

Well for the function of x we have x=t^5+1 and we know t= -1

So you plug in -1 instead of the t and you will get x=(-1)^5+1
Now just resolve that equation to get the value of x

x = (-1)^5+1 = -1+1 = 0 So x=0

Do the same with y and you’ll get y=2
