expand 4(4.24(3.24a^2-900))

expand

4 (4.24 (3.24 a^{2} - 900))

54.9504 a^{2} - 15264

Solution steps

4 (4.24 (3.24 a^{2} - 900))

Remove parentheses:

(a) = a

= 4 \cdot 4.24 (3.24 a^{2} - 900)

Multiply the numbers:

4 \cdot 4.24 = 16.96

= 16.96 (3.24 a^{2} - 900)

Apply the distributive law:

a (b - c) = ab - a c

a = 16.96, b = 3.24 a^{2}, c = 900

= 16.96 \cdot 3.24 a^{2} - 16.96 \cdot 900

= 3.24 \cdot 16.96 a^{2} - 900 \cdot 16.96

Simplify

3.24 \cdot 16.96 a^{2} - 900 \cdot 16.96 : 54.9504 a^{2} - 15264

= 54.9504 a^{2} - 15264
