(x-1)(x-3)(x+5)(x+7)=297
mihalych1998 [28]

First simplify the expression into polynomial form,

(x-1)(x-3)(x+5)(x+7)=297

x^4+8x^3-10x^2-104x+105=297

x^4+8x^3-10x^2-104x-192=0

Now factor into,

(x-4)(x+8)(x^2+4x+6)=0

Which means the solutions are,

x-4=0\implies\boxed{x_1=4}

x+8=0\implies\boxed{x_2=-8}

and then two complex solutions because determinant of the third factor D\lt0,

x^2+4x+6=0

x^2+4x+4=-2

(x+2)^2=-2\implies\boxed{x_3=i\sqrt{2}-2},\boxed{x_4=-i\sqrt{2}-2}

Hope this helps :)

The larger of two numbers is 15 more than three times the smaller number. If the sum of the two
aivan3 [116]

Step-by-step explanation:

Let the smaller number be x

Greater number = 3x + 15

3x + 15 + x = 63

4x + 15 = 63

4x = 63 - 15

4x = 48

x = 48/4

x = 12

Greater number = 3(12) + 15 = 51

Is the expression x3•x3•x3 equivalent to x3•3•3? Why or why not? Explain your reasoning.
Blizzard [7]
It is not because when numbers have an exponent and are multiplied, the exponents are added.
For example:
x^{3} × x^{3} × x^{3} = x^{9}
When a number with an exponent is multiplied with a whole number, the coefficients are multiplied. In this case x^{3} has an imaginary 1 being multiplied to it, so 1 will be multiplied to the other numbers.
1 x^{3} × 3 × 3 = 9x^{3} 
Therefore, the expressions are not the same because the second equation does not have other variables being multiplied to it.
