X^2-3=5x simplify this

1 answer:

7 0

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

Determine the remainder when (5x3 + 49x2 + 74x + 6) is divided by (x + 8).

blondinia [14]

The polynomial remainder theorem says that the remainder when dividing a polynomial $P(x)$ by a linear divisor $x-k$ is simply $P(k)$ .

If $P(x)=5x^3+49x^2+74x+6$ , then the remainder upon dividing by $x+8$ is

$P(-8)=-10$

You could also verify this by actually computing the quotient and remainder.
