Please help me I usually know how to do this but I idk what I am doing wrong
tamaranim1 [39]
Tbh i dont really remember how to this this but the only way i could think of solving it is saying how a spuare/rectangle have all equal sides so if they have all equal sides you can divide that number by 4 so 4/30=7.5 so i would say x = 7.5 tell me if its wrong

~ Good Luck :D ~

(3x^2-11x-4)-(x-2)(2x+3)
eduard

(3x2-11x-4)-(x-2)(2x+3)

Final result :

 x2 - 10x + 2

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (((3•(x2))-11x)-4)-(x-2)•(2x+3)

Step  2  :

Equation at the end of step  2  :

 ((3x2 -  11x) -  4) -  (x - 2) • (2x + 3)

Step  3  :

Trying to factor by splitting the middle term

3.1     Factoring  x2-10x+2

The first term is,  x2  its coefficient is  1 .

The middle term is,  -10x  its coefficient is  -10 .

The last term, "the constant", is  +2

Step-1 : Multiply the coefficient of the first term by the constant   1 • 2 = 2

Step-2 : Find two factors of  2  whose sum equals the coefficient of the middle term, which is   -10 .

     -2    +    -1    =    -3

     -1    +    -2    =    -3

     1    +    2    =    3

     2    +    1    =    3

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

 x2 - 10x + 2

Find the vertex of the graph of the function.<br> f(x) = 2x2 - 8x + 9
Katen [24]

Answer:

(2, 1).

Step-by-step explanation:

f(x)=2x^2-8x+9

Find -b/2a first, it's -(-8)/2(2)=8/4=2.

Then find the y-coordinate of the vertex.

2(2)^2-8(2)+9=2(4)-16+9=8-16+9=-8+9=1
