(2x-7)-(4x^2+6x-3)+(x^2+4)
masha68 [24]

Answer:

-3x^2-4x

Step-by-step explanation:

Simplify:

\left(2x-7\right)-\left(4x^2+6x-3\right)+\left(x^2+4\right)

=2x-7-\left(4x^2+6x-3\right)+x^2+4

Group same factor:

=-\left(4x^2+6x-3\right)+x^2+2x-7+4

Add :

=-\left(4x^2+6x-3\right)+x^2+2x-3

Apply the distributive law: -(a+b) = -a - b

-\left(4x^2+6x-3\right)=-4x^2-6x+3

=-4x^2-6x+3+x^2+2x-3

Group same factor:

=-4x^2+x^2-6x+2x+3-3

Subtract:

=-4x^2+x^2-6x+2x

Add:

=-3x^2-6x+2x

Group same factor:

=-3x^2-4x

Hence answer = -3x^2-4x

Not sure how to do this problem
myrzilka [38]
First we need to write the factors of the polynomial. In order for 1, 4, and -3 to be roots, they need to be the x values that make the polynomial equal 0.

(x - 1) = 0

That would be the factor for x = 1 because when we plug 1 in for x we get 1 - 1 which equals 0.

Multiply all the factors together.

(x-1)(x-4)(x+3)=0

Now FOIL.

(x^2-5x+4)(x+3)

x^3-2x^2-11x+12

Given Sn=2n^2 - 5n, find
brilliants [131]

Answer:

a) -3

b) 117

c) 100

Step-by-step explanation:

(a) 2(1)²-5(1)

1²= 1

2×1= 2

2-5= -3

(b) 2(9)²-5(9)

9²= 81

81×2= 162

162-45= 117

(c) 2(4)²-5(4) +2(8)²-5(4)

4²=16

16×2= 32

32-20= 12

8²=64

64×2= 128

128-40= 88

88+12= 100

hope it helps!

Can someone please answer this for me
marshall27 [118]

Answer:

 B.  5¹³

Step-by-step explanation:

(5²)⁴ * 5⁵

With parenthesis you multiply the exponents:

(5²)⁴ becomes 5⁸

Add exponents when multiplying base numbers are the same:

5⁸ * 5⁵ = 5⁽⁸ ⁺ ⁵⁾ = 5¹³
