x2 - 16 = (x + 4)(x - 4). For a polynomial a2 - b2 = (a + b)(a - b)
4
X2 + 4xx(x + 4)=======
Two numbers differing by 9 whose product is 112? 7 & 16 (x + 7)(x - 16)
x2-196 = (x-14)(x+14) when factored
X2 - 4= (x + 2)(x - 2)===========
X3 + 8= (x+2)(x2-2x+4)
4(x2 + 4)
1(x2-1)
X2 + 4xx(x + 4)=======
x2 + 6x = x*(x + 6)
Two numbers differing by 9 whose product is 112? 7 & 16 (x + 7)(x - 16)
x2-196 = (x-14)(x+14) when factored
38
x3-16xx(x2-16)x(x+4)(x-4)...forgot to finish it, sorry.
x(x+5)
( x - 14 ) ( x + 14 )
X(X2 - X)
x2 - 41 cannot be factorised.
