Question

x^ - 8x +15 find the zeros of the polynomial and relatn blw zeroes and coefficient of the polynomial ​

Answer 1

Answer:

• ${x }^{2} - 8x + 15 = 0$
• $1 \times 15 = 15$
• $15 = 3 \times 5$
• ${x}^{2} - 5x - 3x + 15 = 0$

${ {x}^{2} - 5x} + { - 3x + 15} = 0$

• x(x-5)-3(x-5)=0
• (x-5)+(x-3)=0
• x=5(or)3
• sum of zeroes = -b/a
• $= \alpha + \beta$
• $\alpha = 5$
• $\beta = 3$
• -b/a=8 and
• $\alpha + \beta = 8$
• product of zeroes = c/a
• $\alpha \times \beta$
• c/a =15/1 15
• $\alpha \times \beta = 15$
