Question

Geometrically zero of the quadratic polynomial is

(i) x coordinates of the point where the parabola intersect the x-axis

(ii) y coordinates of the point where the parabola intersect the y-axis

(iii) any point on the graph




b. Two shapes of the parabola either open upwards or open down

words depends on

(i) Coefficient of x

(ii) coefficient of x

2

(iii) constant term



c. Sum of the zeroes of x

2 + 4x - 1 is

(i) 4

(ii) -4

(iii) -1



d. The zeroes of the polynomial x

2

-7 are

(i) 7,-7

(ii) 7,7

(iii) √7,√7



e. The maximum number of zeroes, a quadratic polynomial can have

(i) 3

(ii) 1

(iii) 2​

Answer 1

Answer:

$\longrightarrow⟶ \huge\boxed{\fcolorbox{black}{Pink}{Answer}}$

(i) The zeroes of a quadratic polynomial ax2 + bx + c, a ≠ 0, are precisely the x-coordinates of the points where the parabola representing y = ax2 + bx + c intersects the x-axis.

hence 2nd option is correct ✔

(ii) coefficient of x

(iii) -1

(iv) √7,√7

(v) a quadractic polynomial is the polynomial in which the highest degree is 2. so the maximum number of zeroes/roots/values that it can have => 2.

hence 2 option is correct

and please next time whew you ask questions tell me your board class exercise and question number

thank you
