Answer:

Step-by-step explanation:

f(x) = 2x^2 - 4x + 5 Put brackets around the first 2 terms.

f(x) = (2x^2 - 4x) + 5 Take out the common factor of 2

f(x) = 2(x^2 - 2x) + 5 1/2 the second term and square.

f(x) = 2(x^2 -2x + (2/2)^2) + 5 Express brackets as a perfect square.

f(x) = 2(x - 1)^2 + 5 Multiply 2 * 1 (the term without an x. Subtract.

f(x) = 2(x - 1)^2 + 5 - 2 Combine

f(x) = 2(x - 1)^2 + 3

Use what you know about the difference of squares and the product of a perfect square binomial to expand the following.

Answer:

$\boxed{x^2 - 6x + 9 - y^2}.$

Step-by-step explanation:

We start by applying the difference of squares to the expression:

$((x-3)-y)((x-3)+y) = (x-3)^2 - y^2.$

Now we apply the square of a binomial to the first term:

$(x-3)^2 - y^2 = x^2 - 2 \times 3 \times x + 3^2 - y^2 = x^2 - 6x + 9 - y^2.$

So the answer is:

$\boxed{x^2 - 6x + 9 - y^2}.$

G(x) = 8x - 9 for g(x) = 23

aleksklad [387]

23=8x-9 It’s says g(x)=23 so put 23 where
+9 +9. The g(x) is on the equation.
First, add the 9
32=8x
/8 /8. Then, divide by 8.

4=x. And this should be your answer

Hope this helps! :)
