What value should be added to the expression to create a perfect square? x2 – 10x A. 25 B. –100 C. 5 D. 100
Gnoma [55]
It's important to understand how perfect square trinomials work.

Say we had a factored perfect square trinomial in the form (x - n)²

If we distributed that out we'd have x² + 2nx + n².

Now, take a look at our expression... x² - 10x.
Imagine that 2nx term as 10x...n =5.
In that case, we'd have to add 25 to make our perfect square trinomial

as a rule of thumb: halve the x coefficient, square it, and then add it.

Dorothy is drawing a block on a poster. She knows that the area of the block square cm. Determine which of the following are pos
leva [86]

Answer:

(x-6)(x-1)

Step-by-step explanation:

To find possible dimensions , we need to factor x^2 - 7x + 6

x^2 - 7x + 6

Here sum is -7  and product is 6

-1 times -6 = 6

-1 + (-6) = -7

Now we break -7x using factors -1  and -6

x^2 + 7x + 6

x^2 -6x-1x + 6

Now we do groping

(x^2 -6x)+(-1x + 6)

x(x -6)-1(x-6)

factor out x-6

(x-6)(x-1)
