(6 + 5i)(4 + 7i) = 24 + 42i + 20i + 35i²
= 35i² + 62i + 24
The product of 6+5i and 4+7i is 35i² + 62i + 24.
Commutative is where you are able to move around the numbers to make it easier to add, subtract, divide, or multiply. Associative is where you can put parenthesis around any numbers and add, subtract, ect.
Answer:
Step-by-step explanation:
x = -4 and x=1
The solutions to the equation x^2 +3x -4 = 0 will be given by the points at which the graph intercepts the x-axis.
By looking at the graph, we can clearly see that the graph intercepts the x-axis at x=-4 and x=1.
One of the roots is located between -4 and -3, and the other one between 0 and 1.
