A) <span>5x^2-13x-6
1. First, you must find the roots of the quadratic equation, by applying the quadratic formula, which is:
x=-b</span>√(b²-4ac)/2a
<span>
2. The roots are:
x1=3
x2=-2/5
3. Then, you have:
5(x-3)(x+2/5)
4. When you simplify, you obtain:
(x-3)(5x+2)
B) </span>4x^4-28x^3+48x^2<span>
1. First, you must factor the common term, which is 4x</span>^2. Then:
<span>
4x</span>^2(x^2-7x+12)
<span>
2. Now, you must apply the quadratic formula to obtain the roots of the quadratic equation: </span>x^2-7x+12. Then, you have:
x1=4
x2=3
3. Finally, you obtain:
4x^2(x-4)(x-3)
Answer:
2x-6
Step-by-step explanation:
4(x + 2) = 96
Divide both sides by 4.
= 24
x + 2 = 24
Subtract 2 from both sides.
(x+2) - 2 = 24 - 2
x = 22
Hence, the value of x is 22.
