Question 1084180: What is the answer= 3(x2+7) note x to the 2nd power
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
3 * (x^2 + 7) is solved using the distributive property of multiplication.

it is equal to 3 * x^2 + 3 * 7

the result is 3x^2 + 21.

the general form of the distributive property of multiplication is:

a * (b + c) equals:

a*b + a*c

it is also (a + b) * (c + d) equals:

a*c + a*d plus:
b*c + b*d

the general concept is that each term in the multiplier operates on each term in the multiplicand exactly one time.

in a * (b+c), a is the multiplier and b is the multiplicand.

each term in the multiplier (a) multiplies each term in the multiplicand (b and c) exactly one time.

similarly, in (a + b) * (c + d), a and b in the multiplier, multiply each term (c and d) in the multiplicand, exactly one time each.
