Which of the following is not a correct form of the quadratic function?
aleksklad [387]

Answer:

The squared form is not a correct form of the quadratic function.

Step-by-step explanation:

Given some forms of quadratic equation. we have to choose the form which is not correct of the quadratic equation.

As the general form and the standard form of quadratic equation is

y=ax^2+bx+c where a,b and c are constant.

Also, the vertex form is

y=m(x-a)^2+b where (a,b) is vertex.

Only the three forms of quadratic equation exist. No other form like squared form exist.

Hence, the squared form is not a correct form of the quadratic function.

Help is it A or B? pls help
Damm [24]

Answer:

f(x)=-(x+8)(x-2)

Step-by-step explanation:

Start by factoring out a -1...

f(x)=-(x^2+6x-16)

Now, we have to find two integers that multiply to get -16 and have a sum of 6:

(-2)*8=-16

-2+8=8-2=6

Using this, we can split 6x into -2x and 8x...

f(x)=-(x^2-2x+8x+16)

Factor  the first and second half separately...

f(x)=-[(x^2-2x)+(8x-16)]\\f(x)=-[x(x-2)+8(x-2)]\\

Since both x and 8 are being multiplied by x-2, we can combine them to get...

f(x)=-(x+8)(x-2)
