Answer:

x2 − 15 = 2x
x2 − 2x − 15 = 0
(x − 5)(x + 3) = 0
x − 5 = 0 or x + 3 = 0
Potential solutions are −3 and 5

Step 1: x²-15=2x
step 2: x²-2x-15=0
step 3: (x-5)(x+3)=0
step 4: x-5=0 or x+3=0
step 5: x=5 of x=-3

Evaluate the expression for<br> a = 27, b = 26, c = 27, d = 23:<br> a+b-c-d

artcher [175]

For this case we have the following expression:

$a + b-c-d$

We must evaluate the expression when:

$a = 27\\b = 26\\c = 27\\d = 23$

Substituting the values we have:

$a + b-c-d = 27 + 26-27-23$

Equal signs are added and the same signs are placed.

$a + b-c-d = + 53-50$

Different signs are subtracted and the sign of the major is placed:

$a + b-c-d = 53$

Finally we have to:

$a + b-c-d = 53$

Answer: $a + b-c-d = 53$
