The formula for quadratic equation is given by:
x² - (sum)x + (product) = 0
so if we have real roots of 3 and 5
<span> x² - (3 + 5)x + (3*5) = 0
</span> x² - 8<span>x + 15 = 0
</span>
so if we have real roots of -3 and -6
<span> x² - (-3 - 6)x + (-2*-6) = 0
</span> x² - (-9<span>x) + 12 = 0
</span> x² + 9<span>x + 12 = 0</span>
-4 (2x - 3) > -28
Divide by -4 on both sides. Since we're dividing by a negative, we need to switch the sign.
2x - 3 < 7
Add 3 to both sides
2x < 10
Divide by 2 on both sides
x < 5
Answer:
Step-by-step explanation:
4 times 4 is 16 so while both are in power so we can do this like that
1.7 miles: subtract 1.5 from 3.2 which equals 1.7 (make sure to line up the decimals!)
Answer:
h=6
Step-by-step explanation:
19h-7=23+14h
-7-23=14h-19h
-30=-5h
h=6
