Answer:
x = -7/3 or -5
Step-by-step explanation:
3x^2 + 22x = -35
3x^2 + 22x + 35 = 0
(3x + 7) (x + 5) = 0
so for 3x+7:
3x+7 = 0
3x = -7
x = -7/3
So for x + 5:
x + 5 = 0
x = -5
The vertex and the t-intercept where t>0, will help solve this problem. Sending the work on the attachment.
Answer:
30
Step-by-step explanation:
6*5=30
The quadratic equation in its generic form is:
ax2 + bx + c
To complete squares we must add the following term:
(b / 2) ^ 2
The equation is:
ax2 + bx + c + (b / 2) ^ 2
We have the following equation:
x ^ 2 - 5x + k = 7
By completing squares we have:
x ^ 2 - 5x + (-5/2) ^ 2 = 7 + (-5/2) ^ 2
Rewriting:
x ^ 2 - 5x + 6.25 = 7 + 6.25
Answer:
A constant term should be used to complete the square is:
6.25
