The roots or the Zeros of <span>x^2 – 2x – 15 = 0 would be
C. x=5, -3</span>
Given that: step 1

step 2: subtract 3x both side

Step 3: Add 18 both side:

Step 4: divide both side by 5

Step:6 The value of x is:
x=6
X(x-1)(x^2+4)=(x^2-x)(x^2+4)=(x^4)+(4x^2)-(x^3)-(4x)=(x^4)-x(x^2+4)+(4x^2)
Answer:
q=(1,5) t=(-2,3)r=(3,-1)s=(0,0)
Step-by-step explanation:
Let gradient of original line = m = 1/6
Gradient of line perpendicular to this = -1/m = -6
(Gradient = slope)
