Find the value of the lesser root of x^2 + 12x + 35 = 0.

Answer:

x = - 7

Step-by-step explanation:

Given

x² + 12x + 35 = 0

Consider the factors of the constant term (+ 35) which sum to give the coefficient of the x- term (+ 12)

The factors are + 7 and + 5, since

7 × 5 = 35 and 7 + 5 = 12, thus

x² + 12x + 35 = 0

(x + 7)(x + 5) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x + 5 = 0 ⇒ x = - 5

Thus the lesser root is x = - 7

if 2x+1∠ 8x-2

inequality , treat this problem like any other equation

have the unknown(x) in one side, and the values on the other side

2x-8x < -1-2

-6x< -3  we multiply by -1, do not forget if we multiply by -1 the sign will change
