The LCM for 6 and 18 is 18
Hope this helps.
The answer is:
a=5
b=9
c=0
Explanation:
1. You can use the quadratic formula to solve quadratic equations with the following standard form:
ax²+bx+c=0
2. The quadratic formula is:
x= (-b±√(b^2-4ac))/2a
3. You have the following quadratic equation:
<span>
5x</span>²<span>+9x=0
</span>
4. Then:
<span>
5x</span>²<span>+9x+0=0
a=5
b=9
c=0
5. When you substitute these values into the quadratic formula, you obtain:
x1=-9/5
x2=0</span>
To find x intercept ,
let f(x) = y
therefore y= 8x - 4
in solving for x intercept, me plug in y = 0
thus
8x - 4 =0
solving for x
8x = 4
dividing through by 8
8x/8 =4/8
x =4/8
x =1/2
therefore, the x intercept is 1/2
