Answer:
225
Step-by-step explanation:
Answer:
-a^2 + -4a + 3a + 12
Step-by-step explanation:
FOIL
First terms: -a x a = -a^2
Outside terms: -a x 4 = -4a
Inside terms: 3 x a = 3a
Last terms: 3 x 4 = 12
The difference between 4x and x4 is that the figures are the opposite way round
Write out all the solutions from 1 to 10 and add them together
(1^2+3(1)-2)=2
(2^2+3(2)-2)=8
" = 16
" = 32
" = 38
" = 52
" = 68
" = 86
" = 106
" = 128
Add them together: 530
