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.
