Answer:

x + 3

Step-by-step explanation:

Factor out the greatest common factor from f(x), which is x²

We get f(x) = x²(x + 3)

The (x + 3) factor is a linear component

Lines are in the form of y = mx + b, here we have y = x + 3

Select the two values of x that are roots of this equation. 2x+11x+15= 0

Amiraneli [1.4K]

Answer:

The roots of the equation are x=-3 and x=-2.5

Step-by-step explanation:

The correct quadratic equation is

2x^2+11x+15=0

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$2x^{2} +11x+15=0$

$a=2\\b=11\\c=15$

substitute in the formula

$x=\frac{-11(+/-)\sqrt{11^{2}-4(2)(15)}} {2(2)}$

$x=\frac{-11(+/-)\sqrt{121-120}} {4}$

$x=\frac{-11(+/-)\sqrt{1}} {4}$

$x=\frac{-11(+/-)1} {4}$

$x_1=\frac{-11(+)1}{4}=-2.5$

$x_2=\frac{-11(-)1}{4}=-3$

therefore

The roots of the equation are x=-3 and x=-2.5

Lin spent 5/6 hour on math homework and 1 3/4 hours on science homework how many hours in all did she spend on homework for both

Alenkinab [10]

Answer:2 7/12 hours.

Step-by-step explanation: First, convert 1 3/4 to improper fraction form which will give you 7/4. Then find the common denominator of 5/6 and 3/4. The common denominator is 24. 5/6=20/24. 7/4=42/24. 20/24+42/24= 2 7/12.
