simplify-(5(2)^2(1)-4)/(2(2)(1)^2)

simplify

- \frac{5 ( 2 ) ^{2} ( 1 ) - 4}{2 ( 2 ) ( 1 ) ^{2}}

- 4

Solution steps

- \frac{5 \cdot 2 ^{2} ( 1 ) - 4}{2 ( 2 ) \cdot 1 ^{2}}

- \frac{5 \cdot 2 ^{2} ( 1 ) - 4}{2 ( 2 ) \cdot 1 ^{2}} = - \frac{5 \cdot 2 ^{2} \cdot 1 - 4}{2 \cdot 2 \cdot 1 ^{2}}

= - \frac{5 \cdot 2 ^{2} \cdot 1 - 4}{2 \cdot 2 \cdot 1 ^{2}}

5 \cdot 2^{2} \cdot 1 - 4 = 16

= - \frac{16}{2 \cdot 2 \cdot 1 ^{2}}

Factor the number:

16 = 2 \cdot 8

= - \frac{2 \cdot 8}{2 \cdot 2 \cdot 1 ^{2}}

Cancel the common factor:

2

= - \frac{8}{2 \cdot 1 ^{2}}

Factor the number:

8 = 2 \cdot 4

= - \frac{2 \cdot 4}{2 \cdot 1 ^{2}}

Cancel the common factor:

2

= - \frac{4}{1 ^{2}}

- \frac{4}{1 ^{2}} = - 4

= - 4

x^{2} + 9 x - 20 = 0

∣ x + 1 ∣ > 9

\frac{x}{5 + 9} = \frac{6}{9}

2 x - 2 = 3

3 (x + 1) < 9
