<span> Given polynomial x^2+8x-48 = 0</span>
<span>x^2+12x-4x-48 = 0</span>
<span>x(x+12)-4(x+12) = 0</span>
<span>(x+12)(x-4) = 0</span>
<span>x+12 = 0</span>
Subtract 12 from each side.
<span>x+12-12 = 0-12</span>
<span>x = -12</span>
<span>and x-4 = 0</span>
Add 4 to each side.
<span>x-4+4 = 0+4</span>
<span>x = 4</span>
<span>Roots are -12,4.</span>
Answer:
A
Step-by-step explanation:
Slope = term that multiply x
y intercept = the number without a variable
Answer: The equation is 4 x 3 x 3 = 432
Step-by-step explanation:
X+y=6
2x+y=4
solve the both
x+y=6
- (2x+y=4)
-x = 2
x=-2
substitute the value of x in x+y=6
-2+y=6
y=6+2
y=8
therefore the answer is (-2,8)
Y = 3x - 8
Because y = mx + b, where m is the slope and b is the y-intercept, just substitute the two numbers.
