Answer 3

To solve the equation (1.5x - 0.6) × (0.88 - 0.64x) = 0, we need to find the values of x that satisfy the equation. The equation is quadratic in nature because of the multiplication of two binomials. Let's solve it step by step:

(1.5x - 0.6) × (0.88 - 0.64x) = 0

First, expand the expression:

1.5x * 0.88 - 1.5x * 0.64x - 0.6 * 0.88 + 0.6 * 0.64x = 0

1.32x - 0.96x^2 - 0.528 + 0.384x = 0

Combine like terms:

1.32x + 0.384x - 0.96x^2 - 0.528 = 0

1.704x - 0.96x^2 - 0.528 = 0

Now, the equation is in standard quadratic form (ax^2 + bx + c = 0), where: a = -0.96 b = 1.704 c = -0.528

To solve for x, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

Substitute the values of a, b, and c into the formula:

x = (-(1.704) ± √((1.704)^2 - 4(-0.96)(-0.528))) / (2(-0.96))

x = (-1.704 ± √(2.905344 + 1.216)) / -1.92

x = (-1.704 ± √4.121344) / -1.92

x = (-1.704 ± 2.0309) / -1.92

Now calculate the two possible solutions for x:

1. x = (-1.704 + 2.0309) / -1.92 = 0.1639 / -1.92 ≈ -0.0854
2. x = (-1.704 - 2.0309) / -1.92 = -3.7359 / -1.92 ≈ 1.9441

So, the solutions for the equation are approximately:

1. x ≈ -0.0854
2. x ≈ 1.9441
