What values of x are equivalent to (x − 5)(4x + 3) = 0?

Sagot :

Answer:

x¹= 5

x²= -(3/4)

Step-by-step explanation:

x¹= 5

x²= -(3/4)

Answer: [5,-0.75]

Because anything multiplied by zero is zero, either the first pair of parenthesis is zero or the second pair is zero. Knowing this you take the number to put into x that makes it zero. For the first one it is 5. The second one is -0.75 because you put the 3 on the other side so you have 4x = -3. Then divide by 4 on both sides and you get x. Because there are two pairs of parenthesis, there are two answers.
