Question

0.10 A quadratie polynomial who veroes are 5 and -3 15
(a) x2+2x-15
(b) x-2x+15
(c) x-2x-15
(d) None of this​

Answer 1

Answer:

sum= 2

product= -15

then the polynomial is $x^{2}$ +2x-15

answer; Option: a

Step-by-step explanation:

Answer 2

️⃤

$\huge {\red {\underline {\underline {\mathsf {\blue{answer}}}}}}$

$\boxed{given \: zeroes \: 5 \: and \: - 3}$

$\therefore(x - 5)(x - ( - 3))$

$= > (x - 5)(x + 3)$

$= > x(x + 3) - 5(x + 3)$

$= > {x}^{2} + 3x - 5x - 15$

$= > {x}^{2} - 2x - 15$

so, ur answer is option (b)

$\boxed{{x}^{2} - 2x - 15}$
