expand (1.5a+1.3)(0.4a^2-2a+3)

expand

(1.5 a + 1.3) (0.4 a^{2} - 2 a + 3)

0.6 a^{3} - 2.48 a^{2} + 1.9 a + 3.9

Solution steps

(1.5 a + 1.3) (0.4 a^{2} - 2 a + 3)

Distribute parentheses

= 1.5 a \cdot 0.4 a^{2} + 1.5 a (- 2 a) + 1.5 a \cdot 3 + 1.3 \cdot 0.4 a^{2} + 1.3 (- 2 a) + 1.3 \cdot 3

Simplify

1.5 a \cdot 0.4 a^{2} + 1.5 a (- 2 a) + 1.5 a \cdot 3 + 1.3 \cdot 0.4 a^{2} + 1.3 (- 2 a) + 1.3 \cdot 3 : 0.6 a^{3} - 2.48 a^{2} + 1.9 a + 3.9

= 0.6 a^{3} - 2.48 a^{2} + 1.9 a + 3.9

\frac{( x - 4 )}{( x - 4 ^{2} ) \cdot ( x + 4 )}

(y^{2} - y + 3) (y^{2} + y - 3)

f (x) 5 x - 10

x^{3} - (y - z)^{3}

\frac{5 ( x ^{3} \cdot y ^{5} )}{( y ^{2} \cdot x ^{4} \cdot y ^{5} )}
