Question

The roots of the equation 2x^2 + px + q=0 are (2a + b) and (a +2b) calculate through values of p and q

Answer 1

x = {-0.8, 0.8}

Explanation:

Simplifying

25x2 = 16

Solving

25x2 = 16

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '25'.

x2 = 0.64

Simplifying

x2 = 0.64

Take the square root of each side:

x = {-0.8, 0.8}
