Answer: It's hard to explain without a grid...
The grid method is a written method used to teach children multiplication. It involves partitioning numbers into tens and units before they are multiplied. In some schools the grid method is referred to as the box method of multiplication because children learn to partition numbers into a grid of boxes.
Step-by-step explanation:
Answer:
a. -216, 0 real roots
Step-by-step explanation:
The discriminant of ...
ax² + bx + c = 0
is ...
d = b² -4ac
When we put your equation into the standard form shown above, we get ...
7n² +8n +10 = 0
Then we can identify a=7, b=8, c=10. The discriminant is then ...
d = 8² - 4·7·10 = 64 -280 = -216
___
The interpretation of the discriminant is ...
- < 0; no real roots (2 complex roots)
- = 0; one real root (multiplicity 2)
- > 0; 2 real roots
Your discriminant is -216, so there are 0 real roots.
