Question

Identify the algebraic linear equation from the given expression (a) x2 +x=2​

Answer 1

$x^2 + x - 2 = 0$

$x^2 + 2x - x - 2 = 0$

$x(x+2) -1(x+2) = 0$

$(x-1)(x+2) = 0$

$x - 1 = 0 => x = 1$

$x + 2 = 0 => x + -2$

the roots of the quadratic equation are 1, -2.

the equation is a quadratic equation
