Please I need answers Factorize x²-6x+9

miskamm [114]

Answer:

The factors of the given equation are:

$x^2-6x+9=(x-3)(x-3)=(x-3)^2$

Step-by-step explanation:

We have :

$x^2-6x+9$

Using middle term splitting theorem to factorize the expression :

$x^2-3x-3x+9$

$x(x-3)+(-3)(x-3)$

$(x-3)(x-3)$

$x^2-6x+9=(x-3)(x-3)=(x-3)^2$

The factors of the given equation are:

$x^2-6x+9=(x-3)(x-3)=(x-3)^2$

April and Amy have a combination age oh 53.Amy is 9 years younger than April.what are April and Amy ages.

Lostsunrise [7]

If the total age of both April and Amy are 53

And Amy is 9 years younger than april.

Then to solve for Amy's age you would subtract 9 from 53 and divide by 2

which equals 22

Since amy is 9 years younger than April, then April's age is Amy's age 22 + 9 which gives you 31

April's age is 31 and Amy's age is 22

Which are the solutions of x2 = –13x – 4? 0, 13 0, –13 StartFraction 13 minus StartRoot 153 EndRoot Over 2 EndFraction comma Sta

klasskru [66]

Solution of the given expression $x^2 = -13x-4$ is $x=\frac{-13+\sqrt{153}}{2}\,\,and\,\,x=\frac{-13-\sqrt{153}}{2}$

Correct options are: Start Fraction negative 13 minus Start Root 153 End Root Over 2 End Fraction comma Start Fraction negative 13 + Start Root 153 End Root

Step-by-step explanation:

We need to find solutions of $x^2 = -13x-4$

We need to solve the quadratic equation and find values of x.

Solving:

$x^2 = -13x-4$

Rearranging the terms:

$x^2+13x+4=0$

Solving the quadratic equation using quadratic formula:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

where a = 1, b= 13 and c=4

putting values:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-(13)\pm\sqrt{(13)^2-4(1)(4)}}{2(1)}\\x=\frac{-13\pm\sqrt{169-16}}{2}\\x=\frac{-13\pm\sqrt{153}}{2}\\x=\frac{-13+\sqrt{153}}{2}\,\,and\,\,x=\frac{-13-\sqrt{153}}{2}$

So, Solution of the given expression $x^2 = -13x-4$ is $x=\frac{-13+\sqrt{153}}{2}\,\,and\,\,x=\frac{-13-\sqrt{153}}{2}$

Correct options are: Start Fraction negative 13 minus Start Root 153 End Root Over 2 End Fraction comma Start Fraction negative 13 + Start Root 153 End Root
