Hi! How do you solve this? Step by step??
2 answers:
Answer:
30
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)
30-54+54=30
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
