Question 16666
(x^2 + 4x +5)(x^2 + x - 2), x=-3

((-3)^2+4(-3)+5)((-3)^2+(-3)-2)
Multiply (-3)(-3)=9; two negatives multiplied together = positive;
4(-3)=-12; a negative multiplied by a positve = negative;
(9-12+5)(9-3-2)
(-3+5)(6-2)
(2)(4)=8
You need to be careful of your negatives
Hope you see what you did wrong, when you multiplied (-3)(-3)=-9
Otherwise you did good!
