Question

Dues 19. Afa and ß are the zeroes of the polynomial
4x2 + 3x +7, then find the value of I + 1
B
Ans-​

Answer 1

given Question:

$4 { x}^{2} + 3x + 7$

$4 {x}^{2} + 7x - 4x + 7$

$x(4x + 7) + 1(4x + 7)$

$(4x + 7)(x + 1)$

so the zeros of this polynomial will be

$x = - \frac{4}{7} and \: x = - 1$

and the

$\alpha \: \beta \: of \: the \: polynomial$
