Answer:The solutions are -1 and 2/5
Explanation:The general form of the quadratic equation is:
ax² + bx + c = 0
The given equation is:
5x² + 3x - 2 = 0
By comparison:
a = 5
b = 3
c = -2
Now, to get the roots (solutions) of the equation, we will need to use the quadratic formula shown in the attached image
Substituting in the equation, we would find that:
either x =
or x =

Let's solve your equation step-by-step.
−3(2−5w)=9w+66
Step 1: Simplify both sides of the equation.
−3(2−5w)=9w+66
(−3)(2)+(−3)(−5w)=9w+66(Distribute)
−6+15w=9w+66
15w−6=9w+66
Step 2: Subtract 9w from both sides.
15w−6−9w=9w+66−9w
6w−6=66
Step 3: Add 6 to both sides.
6w−6+6=66+6
6w=72
Step 4: Divide both sides by 6.
<u>6w
</u>

w=12
Answer:
w=12
