Step-by-step explanation:

Substitue 3 for every x in the equation

10(3)-(3*3)(2*3)+(3)^2(2*3)

Multiply

30-(9)(6)+9(6)

Answer:

=30

Step-by-step explanation:

Substitute the variable

10(3)- (3(3)) (2(3))+ 3^2 (2(3))

Multiply the numbers

10×3-(3×3)×(2×3)+3^2×(2×3)

10×3-9×6+9×6

Eliminate the opposites

10×3=30       *9×6+9×6 these are the opposites

<u>OR THERE'S ANOTHER WAY</u>

10x-(3x)×(2x)×x^2×(2x)

Remove unnecessary parenthesis

10x-3x×2x×x^2×2x

Calculate the product

10x-6x^2+2x^3

Use the commutative property to reorder the terms

2x^3-6x^2+10x

Substitute the variable

2×3^3-6×3^2+10×3

=30
