Please simplify with steps:
(4a+4)^2-4*a^2*4
(Im calculating the discriminent of a quadratic)
Simplify the following:
(4 a+4)^2-4×4 a^2
-4×4 = -16:
(4 a+4)^2+-16 a^2
(4 a+4) (4 a+4) = (4 a) (4 a) + (4 a) (4) + (4) (4 a) + (4) (4) = 16 a^2+16 a+16 a+16 = 16 a^2+32 a+16:
16 a^2+32 a+16-16 a^2
Grouping like terms, 16 a^2-16 a^2+32 a+16 = 32 a+(16 a^2-16 a^2)+16:
32 a+(16 a^2-16 a^2)+16
16 a^2-16 a^2 = 0:
32 a+16
Factor 16 out of 32 a+16:
Answer: |
| 16 (2 a+1) =32a + 16
