4^x+2=1/2 solve for x (log equation)

lesantik [10]

$\log_ab=c\iff a^c=b\\\\4^{x+2}=\dfrac{1}{2}\qquad\text{use}\ a^{-1}=\dfrac{1}{a}\\\\(2^2)^{x+2}=2^{-1}\qquad\text{use}\ (a^n)^m=a^{nm}\\\\2^{2(x+2)}=2^{-1}\iff2(x+2)=-1\qquad\text{use distributive property}\\\\(2)(x)+(2)(2)=-1\\\\2x+4=-1\qquad\text{subtract 4 from both sides}\\\\2x=-3\qquad\text{divide both sides by 2}\\\\\boxed{x=-1.5}$

7x^2+8=18x Need help learning factoring please put work so I can understand

Zigmanuir [339]

Answer:

(x - 2)(7x - 4)=0

Step-by-step explanation:

$7 {x}^{2} + 8 = 18x \\ 7 {x}^{2} - 18x + 8 = 0 \\ 7 {x}^{2} - 14x - 4x + 8 = 0 \\ 7x(x - 2) - 4(x - 2) = 0 \\ (x - 2)(7x - 4) = 0$

What is a third-degree polynomial function P(x) with rational coefficients so that P(x) = 0 has roots −3 and i?

Mandarinka [93]

Answer:

x²-(i-3)x- 3i

Step-by-step explanation:

What is a third-degree polynomial function P(x) with rational coefficients so that P(x) = 0 has roots −3 and i?

Given the toots of the polynomial to be -3 and i, the factors of the polynomial will be (x+3) and (x-i)

Taking the product

P(x) = (x+3)(x-i)

P(x) = x²-xi+3x-3i

P(x) = x²-(i-3)x- 3i

Hence the required polynomial is

x²-(i-3)x- 3i
