Answer:
(7c + 5d)²
Step-by-step explanation:
In order to factor a quadratic equation, we need to look at the coefficients of all the terms. In this case the following quadratic:
49c² + 70cd + 25d², has an 'a' = 49, 'b' = 70 and 'c' = 25.
When we take the √49 = 7 and the √25 = 5, we can see that when we multiply 7 x 5 = 35 and 35 + 35 = 70, so we know that our two equations will be the same: (7c + 5d)
Using the FOIL (forward, outside, inside, last) method, we can check our answer:
(7c + 5d)(7c + 5d) = 49c² + 35cd + 35cd + 25d² or 49c² + 70cd + 25d²

Step-by-step explanation:
(7 x 10^*9)(5.6 x 10^*8)
(7000000000)(560000000)
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
If the decimal is moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
