Question

(x - 3) (3x + 7) = 0 Find the values of x.

Answer 1

(x-3)(3x+7)=0
x-3=0 or 3x+7=0

1. x-3=0
x₁=3

2. 3x+7=0
3x=-7
x₂=-7/3 = -2(1/3)

Answer 2

Answer:

The values of x is, $3$ or $\frac{-7}{3}$.

Step-by-step explanation:

$(x - 3) (3x + 7) = 0$

Using Zero Factor principle:

Since the factors are in the factorize form and their product is equal to zero.

so, equate each factor equals to zero and solve for the values of x.

then, $(x-3)=0$  ⇒$x=3$

and $(3x+7)=0$ ⇒$x=\frac{-7}{3}$

Therefore, the values of x is, $3$ or $\frac{-7}{3}$.
