Solve (3.15)^3-6(3.15)^2+8(3.15)

$$( 3.15 ) ^ { 3 } - 6 ( 3.15 ) ^ { 2 } + 8 ( 3.15 )$$

Evaluate

$$-3.079125$$

Solution Steps

Calculate 3.15 to the power of 3 and get 31.255875.

$$31.255875-6\times 3.15^{2}+8\times 3.15$$

Calculate 3.15 to the power of 2 and get 9.9225.

$$31.255875-6\times 9.9225+8\times 3.15$$

Multiply 6 and 9.9225 to get 59.535.

$$31.255875-59.535+8\times 3.15$$

Subtract 59.535 from 31.255875 to get -28.279125.

$$-28.279125+8\times 3.15$$

Multiply 8 and 3.15 to get 25.2.

$$-28.279125+25.2$$

Add -28.279125 and 25.2 to get -3.079125.

$$-3.079125$$
