check whether x² +4x +4 is prefect spuare expression or not . if so factorise the expression

Answers

Answer:

It is a perfect square expression.

It factors to (x+2)^2

===========================================================

Explanation:

The general format for a perfect square is

(a+b)^2 = a^2 + 2ab + b^2

Which can be seen through the use of the FOIL rule.

Compare x^2+4x+4 with a^2+2ab+b^2, and we have these three equivalences:

x^2 = a^2 .... first terms4x = 2ab .... middle terms4 = b^2 .... last terms

Since x^2 = a^2, we can apply the square root to both sides to get a = x. Similarly, 4 = b^2 leads to b = 2. We could get b = -2, but that would mean 2ab = 2x*(-2) = -4x instead of 4x. So we'll stick with b = 2 instead.

Because a = x and b = 2, we then can say:

(a+b)^2 = a^2 + 2ab + b^2

(x+2)^2 = x^2 + 2*x*2 + 2^2

(x+2)^2 = x^2 + 4x + 4

Showing that x^2+4x+4 factors to (x+2)^2.

Answer:

  (x, y) = (40, 11/3)

Step-by-step explanation:

The variable x can be eliminated by subtracting the first equation from the second.

  (x -9y) -(x -12y) = (7) -(-4)

  3y = 11 . . . . . . .simpify

  y = 11/3 . . . . . .divide by 3

  x -9(11/3) = 7 . . . . substitute for y in the second equation

  x = 40 . . . . . . . add 33

The solution is (x, y) = (40, 11/3).

Write a quadratic equation ax²+ bx + C = 0, whose coefficients are a =-9, b = 0, c = -2

Please I really need your help for this ​

Answers

ax² + bx + c = 0

Let's write -9 where we see A:

-9x² + bx + c = 0

Let's write 0 where we see B:

-9x² + 0.x + c = 0

(Since B = 0, when it is multiplied by x, it becomes 0 again)

-9x² + c = 0

Let's write -2 where we see C:

-9x² + -2 = 0

Now we can move on to solving our equation:)

Let's put the known and the unknown on different sides:

(-2 goes to the opposite side positively)

-9x² = 2

(it goes as a division because it is in the case of multiplying -9 across)

x² = 2/-9

The quadratic equation ax²+ bx + C = 0, whose coefficients are a = -9, b = 0, c = -2 will be -9x² + -2 = 0

What is the equation?

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that,coefficients fore the equation,ax²+ bx + C = 0, is a =-9, b = 0, c = -2

We have to write a quadratic equation as,

Any equation of the form ax²+bx+c=0  where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

ax² + bx + c = 0

-9x² + 0x + (-2) = 0

-9x² + -2 = 0

-9x² + -2 = 0

Thus, the quadratic equation ax²+ bx + C = 0, whose coefficients are a =-9, b = 0, c = -2 will be -9x² + -2 = 0
