Multiply
(x+a)(x+b) = x^2 + bx + ax + ab
looking at; x^2 + 10x + 24
can you see that
ab = 24
bx + ax = 10x
then
a + b = 10
use substitution: a = 10 - b
(10-b)b = 24
10b - b^2 = 24
-b^2 + 10b -24 = 0
now find the values for b using the quadratic equation. I'm on my phone so you'll have to plug the numbers in. let me know if you have any questions.
Answer:
(x+7)
Step-by-step explanation:
(x+7)(2x+1)=2x^2+14x+x+7=2x^2+15x+7
Yo sup??

Hope this helps you. I apologize if it’s incorrect.
Our goal is to get r all by itself on one side of the equals sign. To do this, we'll first add s to both sides
k=2r-s
+s +s
k+s=2r
Now, to get r alone, we need to get rid of the 2. Since 2 is multiplied by r, we need to divide it from both sides to get r alone.
k+s=2r
/2 /2
(k+s)/2=r
Since there are no numbers, that's the final answer.
