Answer:
(2x² + 5x + 2) = (2x + 1)(x +2)
Step-by-step explanation:
Given expression is (2x² + 5x + 2).
We have to factorize the given expression.
(2x²+ 5x + 2) = 2x² + 4x + x + 2
= 2x(x + 2) + 1(x + 2)
= (2x + 1)(x + 2)
So the factored form of the given expression will be (2x + 1)(x + 2).
Simplify the following:
(-6 (-8)×2×3 x x x x)/(3×4)
(8 x×2 x (-6) x×3 x (-1))/(3×4) = (8 x^4×2 (-6)×3 (-1))/(3×4):
(-6 (-8)×2×3 x^4)/(3×4)
8×2 = 16:
(-6 (-3)16 x^4)/(3×4)
16 (-6) = -96:
(-3-96 x^4)/(3×4)
-96 (-3) = 288:
(288 x^4)/(3×4)
3×4 = 12:
(288 x^4)/12
