(b + 8)(b + 4)
No.
No.
-2x2+32 -2(x2-16) -2(x+4)(x-4)
If you mean -(x^2) - 4x + 32, then a simple way to do this is to factor out -1 first: -((x^2) + 4x - 32). Then you need simply to factorise the part inside the brackets
(b + 8)(b + 4)
(x - 8)(x - 4)
No.
No.
(b+8)(b+4)
It is: (c-4)(c-8) when factored
-2x2+32 -2(x2-16) -2(x+4)(x-4)
If you mean -(x^2) - 4x + 32, then a simple way to do this is to factor out -1 first: -((x^2) + 4x - 32). Then you need simply to factorise the part inside the brackets
Pull out the common factor of 2 ... 2(y^2+6y-16) Then just factor (y^2+6y-16) ... (y-2)(y+8)
16 is an even, square, two-digit factor of 32.
2752 = 75625 42 = 16 32 = 9 22 = 4 75625/16 + 9 + 2 = 4737.5625
2^2 + 3^2 = 4 + 9 = 13
