✔ 最佳答案
-9x -36x^4=-9x(1+4x^3) answer//
(x-9)(x+4) +(x-9)(5x-3)
=(x-9)[x+4+5x-3]
=(x-9)(6x+1)answer//

-9x -36x^4
gcf of – 9 and – 36 is (– 9)
out of two numbers if the smaller number divides the greater number then smaller number is gcf and greater number is LCM
out of x and x^4, the term having smaller exponent is gcf and highest exponent is LCM
so x is gcf
so total gcf is – 9x
-9x -36x^4
= – 9x(1 + 4x³)
(x-9)(x+4) +(x-9)(5x-3)
= (x – 9)(x + 4 + 5x – 3)
= (x – 9)(6x + 1)
= 6x² – 53x – 9)

element each and each expression: a million.) 36x^4 - 48x^3 + 9x^2 - 12x = 3x (12x^3 - 16x^2 +3x - 4) 2.) 2c^2 + 20c + 50 = 2(c^2+10c+25) = 2(c+5)(c+5) 3.) 3x^2 - 14x + 11 discriminant 196-4(3)(11) = sixty 4 sqrt64 = 8 x = (14-8)/6 = 6/6 = a million and x = (14+8)/6 = 22/6 = 11/3 = 3(x-a million)(x-(11/3) ) 4.) 5m^2 - 40 5 = 5(m^2-7) = 5(m-sqrt7)(m+sqrt7)

1)
-9x - 36x^4
= -9(x + 4x^4)
= -9x(1 + 4x^3)
2)
(x - 9)(x + 4) + (x - 9)(5x - 3)
= (x - 9)[(x + 4) + (5x - 3)]
= (x - 9)(x + 4 + 5x - 3)
= (x - 9)(6x + 1)
-9x - 36x^4
= -9(x + 4x^4)
= -9x(1 + 4x^3)
2)
(x - 9)(x + 4) + (x - 9)(5x - 3)
= (x - 9)[(x + 4) + (5x - 3)]
= (x - 9)(x + 4 + 5x - 3)
= (x - 9)(6x + 1)

factor out -3x
-3x(3+12x^3)
x^2-5x-36+5x^2-17x+27
then add like terms and the answer is
6x^2-22x-9
i thinkk this is right, I'm not 100% sure
-3x(3+12x^3)
x^2-5x-36+5x^2-17x+27
then add like terms and the answer is
6x^2-22x-9
