Best Answer

The answer would be 3x if 'X2' is '2x', but if 'X2' is x2, then the total answer would be x2 + x.

x4 +x2 =x2 (x2+1)

x2+bx+ax+ab = x2+ax+bx+ab = x(x+a)+b(x+a) = (x+a)(x+b)

x2 + 8x + 15 = (x + 3)(x + 5)

x2 + 12x + 27 = (x + 9)(x + 3)

(x2 + 14 + 48 / (x + 8) = (x2 + 62) / (x + 8) =(x2 + 8x - 8x - 64 + 126) / (x + 8) = x - 1 + 126/(x+8)

The value of x2+7x+10 depends on the value of X. If x=1, then x2+7x+10 = 18 If x=2, then x2+7x+10 = 28 If x=3, then x2+7x+10 = 40 and so forth

The factors of x2 are x and x x times x plus 1 = x2 + x

x4 +x2 =x2 (x2+1)

x4 - 1.We can not "solve" this as we have not been told the value of x. However, we can simplify this expression:We have an x and a minus x here which will cancel out. Likewise the x2 and x3 will cancel out with the -x2 and -x3 respectively. This therefore leaves us with just x4 - 1.

2x3 + x2 + 15 This is a 3rd order polynomial in 'x'. It's numerical value kinda depends on the value of 'x'.

(x2+10x+21)/(x+3) = (x+7)

x2+bx+ax+ab = x2+ax+bx+ab = x(x+a)+b(x+a) = (x+a)(x+b)

The value of the expression x2 + 9 will depend on what value you plug in for x. If you are looking to factor that expression, it can only be done using complex numbers:x2 + 9 = (x + 3i)(x - 3i)
