Answer:

7(x-2)(x+2)

Step-by-step explanation:

7x^2 -28

Factor out a 7

7(x^2 -4)

The terms inside the parentheses is the difference of squares, so it is factorable (a^2-b^2) = (a-b)(a+b)

7(x-2)(x+2)

What is the ratio of 364:78

Klio2033 [76]

You'd want to simplify that by dividing both terms by the greatest common factor which is the product of the shared primes of both numbers prime factorization...

364=2*2*7*13, 78=2*3*13, so the GCF is 2*13=26, now divide both terms by 26

The cubic polynomial below has a double root at r4 and one root at x = 6 and passes Through the point (2, 36) as shown. Algebrai

qaws [65]

The graph in the question is missing.

Answer:

y = $\frac{-1}{4}( x^3 + 2x^2 - 32x -96)$

Step-by-step explanation:

The function is cubic

It has roots as -4, -4 , 6

this means the value of x = -4, -4 , 6 which makes the entire equation zero

so we have solutions as

x+4 = 0

x- 6 = 0

on forming a cubic equation using these

(x+4)(x+4)(x-6)

the equation passes through (2,36)

put x = 2

(2+4)(2+4)(2-6) = (6)*(6)*(-4)

which exceeds 36 so we product the equation with -1/4 to get 36

Final equation

y = $\frac{-1}{4} (x+4)(x+4)(x-6)$

y = $\frac{-1}{4}( x^3 + 2x^2 - 32x -96)$
