Solve by factoring x^2 -9x-52=0

x=13, x=-4

Step-by-step explanation:

please :))

Step  1  :

Trying to factor by splitting the middle term

1.1     Factoring  x2-9x-52

The first term is,  x2  its coefficient is  1 .

The middle term is,  -9x  its coefficient is  -9 .

The last term, "the constant", is  -52

Step-1 : Multiply the coefficient of the first term by the constant   1 • -52 = -52

Step-2 : Find two factors of  -52  whose sum equals the coefficient of the middle term, which is   -9 .

     -52     +    1     =    -51  

     -26     +    2     =    -24  

     -13     +    4     =    -9     That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -13  and  4

                    x2 - 13x + 4x - 52

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-13)

             Add up the last 2 terms, pulling out common factors :

                   4 • (x-13)

Step-5 : Add up the four terms of step 4 :

                   (x+4)  •  (x-13)

            Which is the desired factorization

 (x + 4) • (x - 13)  = 0

-4, 13

Step-by-step explanation:

x²-9x-52=0

Delta=(-9)²-4×1×(-52)=81+208=289=17²

x1=(-(-9)+sqrt(delta))/2=(9+17)/2=26/2=13

x2=(-(-9)-sqrt(delta))/2=(9-17)/2=-8/2=-4

So:

x²-8x-52=(x-13)(x+4)=0

Solutions: x=13 and -4

step-by-step explanation:

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
