Hello from MrBillDoesMath!

Answer:

0

Discussion:

For the quadratic ax^2 + b^x + c, the discriminant is b^2 - 4ac. In our case, the discriminant is

(-20)^2 - 4 (4)(25) =

400      - 4 (100)   =

0

(This means the polynomial has a duplicate root. In fact it factors as          (2x-5)^2       ).


Thank you,

MrB

What numbers multiply to -30 and add to -3
krek1111 [17]
Let the numbers be x and y.  Then xy = -30 and  x+y = -3.

Solve xy = -30 for y:    y = -30/x

subst. -30/x for y in   x+y= -3:     x  -  30/x = -3

Multiply all 3 terms by x:  x^2 - 30 = -3x, so   x^2 + 3x - 10 = 0

Solve this quadratic equation for x.     x: {-5, 2}

If x = -5, then   x+y = -3 becomes -5 + y = -3, and y = 2.

You should check to determine whether x=2 is also correct.  If it is, what is the corresponding y value?

Factor as the product of two binomials x^2-3x-10
cestrela7 [59]

Answer:

(x-5)(x+2)

Step-by-step explanation:

Hello there!

Your expression there has a highest power of x^{2}, so there will be two constants that you need to find.

Your last term is -10, so the constants will have a product of -10. Also your middle term is -3x, so the terms will add up to -3

-5 and 2 fit the mold.

Have a great day!
