13-c=5

13-c-13=5-13

-c= -8

-c/-1 = -8/-1

Factor the expression below:<br> X^2-10x+25

vitfil [10]

$\textbf{ \underline{Using middle term splitting:}} \\ \\ {x}^{2} - 10x + 25 \\ = {x}^{2} - 5x - 5x + 25 \\ = x(x - 5) - 5(x - 5) \\ = (x - 5)(x - 5) \\ = {(x - 5)}^{2}$
___________________________

$\textbf{ \underline{Using identity: }} \underline{ {(a - b)}^{2} = {a}^{2} - 2ab + {b}^{2} }\\ \\ {x}^{2} - 10x + 25 \\ = {(x)}^{2} - 2 \times 5 \times x + {(5)}^{2} \\ = {(x - 5)}^{2}$

Solve: 6-t/2t+9 = -2

dangina [55]

<span>6-t/2t+9 = -2
multiply both sides by 2t+9
which will give you
6-t= -2(2t+9)
6-t = -4t + 18
now add 4t to both sides
6 -t + 4t = -4t -18 + 4t
6 + 3t = -18
6-6 + 3t = -18 -6
3t = -24
t = -24/3
t= -8 (negative 8)
