What's is the square root of 63

QveST [7]

You want to be finding out what two factors (where one of them is a perfect square) has the produce of 63. It seems like 9 x 7 (9 is the perfect square) works.

$\sqrt{63} = \sqrt{9 \times 7} = \sqrt{9} \times \sqrt{7}$

The square root of 9 is 3 so we can just have $3 \sqrt{7}$ (which just means 3 times the square root of 7).

Determine if x + 2 is a factor of p(x) = x 4 + 3x 3 + 4x 2 - 8 and explain why.

Andrej [43]

The Factor Theorem says (x - a) is a factor of function p(x) if p(a)=0

so check for p(-2)

= -2^4 +3(-2)^3 + 4(-2)^2 - 8

= 16 - 24 +16 -8

= 0

so (x + 2) is a factor
