Answer:
(x-3)(x-5)
Step-by-step explanation:
X^2-8x+15
Break the expression into groups
(x^2-3x)+(-5x+15)
Factor out x from x^2-3x
Factor out -5 from -5x+15: -5(x-3)
=x(x-3)-5(x-3)
Factor out common term x-3
=(x-3)(x-5)
Thanks for letting me help!!
Ok
First factor out the first 2 terms as follows:-
y = 1/2(x^2 - 8x) + 21
Now complete the square on x^2 - 8x:-
y = 1/2[ (x - 4)^2 - 16] + 21
y = 1/2(x - 4)^2 - 8 + 21
y = 1/2(x - 4)^2 + 13 Answer
If \dfrac{x-1}{3}=k 3 x−1 =kstart fraction, x, minus, 1, divided by, 3, end fraction, equals, k and k=3k=3k, equals, 3, what i
earnstyle [38]
For this case we have the following expression:
(x-1) / (3) = k
Substituting the value of k = 3 we have:
(x-1) / (3) = 3
From here, we must clear the value of x.
We have then:
x-1 = 3 * 3
x-1 = 9
x = 9 + 1
x = 10
Answer:
The value of x is given by:
x = 10
