Here is a quadratic equation x^2 + 5x = 14
x^2 + 5x - 14 = 0 - Subtract 14 from both sides
(x + 7)(x - 2) = 0 - Factor
x + 7 = 0 x - 2 = 0 - Set each factor equal to 0
x = -7 x = 2 - solve each piece
If the constant is easy to find factors of then use the factoring method
If the constant is difficult and you have a graphing calculator, then graph
If no graphing calculator then use the quadratic formula
Answer:
A. 2/3
Step-by-step explanation:
Simplify it by four, 8 / 4 = 2, 12 / 4 = 3
The equation would be -5+(-12), so the answer would be -17 :)
First you would have to find the base which would be 9^2 + 9^2= C^2 because of the pythagorean theorem. So the base would equal 12.7. To find the area of a triangle it’s A= h•b / 2. So your answer would be 95.25
Answer:
<
Step-by-step explanation:
-4.2 + 1.5 = -2.7 and -5.4 + 2.1 = -3.3
-2.7 is less than -3.3
