2x^{3}+30xx^{2} +72x=0 solve using zero product property

Goshia [24]

Answer:

Values of x are: x=0 or x=-3 or x=-12

Step-by-step explanation:

The equation given to solve using zero product property is $2x^3+30x^2+72x=0$

Zero property rule states that if ab=0 then a=0 or b=0

Taking x common from the equation:

$2x^3+30x^2+72x=0\\x(2x^2+30x+72)=0\\$

Applying zero product rule

$x(2x^2+30x+72)=0\\x=0 \ or \ 2x^2+30x+72=0$

Now, solving $2x^2+30x+72=0$

Using quadratic formula to find value of x

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Putting values

$$x=\frac{-30\pm\sqrt{(30)^2-4(2)(72)}}{2(2)}$\\$x=\frac{-30\pm\sqrt{324}}{4}$\\$x=\frac{-30\pm18}{4}$\\$x=\frac{-30+18}{4} \ or \ x=\frac{-30-18}{4}$ \\x=-3 \ or \ x=-12$

So, Values of x are: x=0 or x=-3 or x=-12

If f(x)=-2x+5, what is f(-3x) equal to?

jekas [21]

Answer:

$f(-3x) = 6x + 5$

Step-by-step explanation:

<u>Step 1: Substitute -3x for x</u>

<u /> $f(x) = -2x + 5$

$f(-3x) = -2(-3x) + 5\\$

$f(-3x) = 6x + 5$

Answer: $f(-3x) = 6x + 5$

*Will give brainiest. Tina invests $1000 in an account that pays an interest rate of 6.75%. A=P(1+r)^t.

bezimeni [28]

A=P(1+r)^t
18600=1000(1+0.0675)^t
18600/1000= (1.0675)^t
18.6= (1.0675)^t
log 18.6 = t log 1.0675
t= log 18.6/ log 1.0675
t=44.75 years
