## Solve by factoring and using the principle of zero products (x – 10)(x – 6) = -3?

(x – 10)(x – 6) = -3. Expand out the brackets on the left hand side to get
x² -16x + 60 = -3. Add 3 to both sides of the equation to get
x² -16x + 63 = 0. Factorise the left hand side. Are there two numbers that add to -16 and multiply to +63? Yes, there is, -7 and -9, so the equation factors to

(x – 7)(x – 9) = 0. Since two numbers can only multiply to zero if one (or both) of them is zero. But x cannot have two different values at the same time, so they can’t both be zero.

So either x – 7 = 0 (and therefore x = 7) or x – 9 = 0 (and therefore x = 9).

Your solutions are therefore 7 and 9.

## solve by factoring and using the principle of zero products (x-10)(x-6)=-3?

(x-10)(x-6)=-3

X^2 -10x – 6x + 60 = -3

x^2 – 16x +63 = 0

What two numbers multiply to give 63? 7 and 9

(x-9)(x-7) = 0 (check that this is correct)

x = 9 or x = 7 are the 2 solutions

## Best Skin care products? x 10 points?

Hii x well i wna buy sum new products for my skin (face wash, toner n moisturizer n possibly sumfin else if u advise me 2) x my skin is kinda wierd lol sum days its combination (moistly oily in areas such as the nose) n nw mst recently its been rlly dry.. so i dnt kno wot 2 get! n also ive started to get loadz of spots! cnt b cause of my diet coz im quite healthy n i exercise so i dno wot 2 do..
