X² + 3x = 10
Convert to standard form.
x² + 3x - 10 = 0
factor x² = x * x
factor -10 = 5 * -2
(x + 5) (x - 2) = 0
x(x -2) + 5(x-2) = 0
x² - 2x + 5x - 10 = 0
x² + 3x - 10 = 0
x + 5 = 0 x² + 3x = 10
x = -5 -5² + 3(-5) = 10
25 - 15 = 10
10 = 10
x - 2 = 0 x² + 3x = 10
x = 2 2² + 3(2) = 10
4 + 6 = 10
10 = 10

Rational is defined as being able to write it as a fraction. 2.22/ 2 = 1.11 which is 1 11/100
Answer:
The answer is in the photo
Step-by-step explanation:
<u>solu</u><u>tion</u>
<u>-4t</u> < <u>12</u> 3t-15<-3
-4 -4 3t<-3+15
t>-3 <u>3t</u><<u>12</u>
3 3
t<4
therefore the numbers that makes both equations right is -3<t<4
