<span>(x+4)(x+1) = m+2x
x² + 5x + 4 − m − 2x = 0
x² + 3x + (4−m) = 0
Quadratic equation has exactly one real solution
when discriminant = 0
b² − 4ac = 0
3² − 4(1)(4−m) = 0
9 − 16 + 4m = 0
−7 + 4m = 0
4m = 7
m = 7/4

Second problem:
Line y = 3 intersects graph of y = 4x² + x − 1 at point A and B
y-coordinates of points A and B = 3, since they are both on line y = 3. We need to find x-coordinates
4x² + x − 1 = 3
4x² + x − 4 = 0
x = (−1 ± √(1−4(4)(−4))) / 8
x = (−1±√65) / 8
AB = (−1+√65)/8 − (−1−√65)/8 = 2√65/8 = √65/4 = √(65/16)
m−n = 49</span>
I have take the answer from internet, I hope it help
Common ratio = 22/-11 = -2 also -76 / 88 = -2 confirms it.
B/ a0 = -11 / -2 = 5.5 and a1 = 88 / -2 = -44
Answer:
x^6/2
Step-by-step explanation:
simplify the expression, 4x^4x^3/8x, you make it 4x^7/8x
and it simplifys to 4x^6/8 which then becomes x^6/2
extra note:
a^x * a^y = a^ x+y
