The first thing you must do is to find factors that equal to -10
1 x -10, -10 x 1, -2 x 5 and -5x 2. Then of these four groups of factor we chose the one that when the two factors are added equals to 3. So -2 x 5 equals 3
So are answer is
(x-2)(x+5)

Answer:

(x-2)(x+5)

Step-by-step explanation:

when factoring, our equation should be in this format: (x+__) (x+__) Then we have to find numbers that add up to 3 but multiply to -10 aka -2 and 5. -2+5=3 and -2(5)= -10

A line that includes the point (–1,4) has a slope of 1/4. What is its equation in SLOPE-INTERCEPT form?
Travka [436]

Answer:

y=0.25x+4.25

Step-by-step explanation:

<u>Step 1:  Determine the two forms</u>

Point Slope Form → (y-y_1)=m(x-x_1)

Slope Intercept Form → y=mx+b

<u>Step 2:  Plug into point slope form</u>

(y-4)=0.25(x-(-1))

y-4=0.25(x+1)

<u>Step 3:  Convert to slope intercept form</u>

y-4+4=0.25x + 0.25+4

y=0.25x+4.25

Answer:  y=0.25x+4.25

Solve for x in the equation x^2+2x+1=17​
dybincka [34]

Answer:

x= (-1+ √17) or (-1-√17)

Step-by-step explanation:

In this question, we have to solve for x from the given equation x² +2x+1 =17

Now, the equation can be rearranged to x² +2x -16 =0.

Here we can not apply the process of factorization to get the value of x.

Hence, we will use the Shridhar Acharya formula to solve the value of x.

{This formula gives, if ax² +bx +c =0 then, the value of x can be solved as

x=[-b±√(b²-4ac)]/2a }

Hence, in this case, the solution for x will be

x=\frac{-2+\sqrt{2^{2}-4(1)(-16) } }{2(1)} or  \frac{-2-\sqrt{2^{2}-4(1)(-16) } }{2(1)}

⇒ x=\frac{-2+2\sqrt{17} }{2} or  \frac{-2-2\sqrt{17} }{2}

⇒ x= (-1+ √17) or (-1-√17) (Answer)
