You need to use the distribute property.
Multiply the 4x and 7x and you will get 28x².
Multiply the 4x and -3 and you will get -12x.
Final answer: 28x² - 12x

Multiply by 4 first.
4x (7x-3)
= x [4 (7x-3)]
= x [4 (7x) - 4 (3)]
= x [28x - 12]
Now multiply by x.
= x (28x) - x (12)
= 28x^2 - 12x
Note: x plus x is 2x but x times x is x^2.
4x (7x-3)
= x [4 (7x-3)]
= x [4 (7x) - 4 (3)]
= x [28x - 12]
Now multiply by x.
= x (28x) - x (12)
= 28x^2 - 12x
Note: x plus x is 2x but x times x is x^2.

4×(7×-3)=4×(-21)
=-84
if x stands for multiplication here...
Otherwise;
4x(7x-3)=4x×7x-4x×3
=28x²-12x
=-84
if x stands for multiplication here...
Otherwise;
4x(7x-3)=4x×7x-4x×3
=28x²-12x

4x (7x-3)
= x [4 (7x-3)]
= x [4 (7x) - 4 (3)]
= x [28x - 12]
Now multiply by x.
= x (28x) - x (12)
= 28x^2 - 12x
or
28x^2-12x
28x^2=12x
(28x^2)/x=12
28x=12
x=12/28
x=3/7
to check the answer you can put 3/4 for the value of x
4(3/4)(7(3/4)-3)
3(21/4-3)
63/4-9=(63-36)/4
27/4
the answer is 27/4
Note: x plus x is 2x but x times x is x^2.
= x [4 (7x-3)]
= x [4 (7x) - 4 (3)]
= x [28x - 12]
Now multiply by x.
= x (28x) - x (12)
= 28x^2 - 12x
or
28x^2-12x
28x^2=12x
(28x^2)/x=12
28x=12
x=12/28
x=3/7
to check the answer you can put 3/4 for the value of x
4(3/4)(7(3/4)-3)
3(21/4-3)
63/4-9=(63-36)/4

the answer is 27/4

4x(7x - 3)
= 28x^2 - 12x
= 28x^2 - 12x
2015-02-02 10:18 pm
4x(7x - 3) =
28x^2 - 12x.
28x^2 - 12x.
2015-02-02 9:29 pm
4x(7x-3) = 28x^2 - 12x
2015-02-02 8:38 am
4x(7x - 3) = 28x^2 - 12x
