Question

if α and β are the zeroes of the quadratic polynomial p(x) = 4x^2 – 5x – 1, then alpha sq + beta sq=?
pls find who ever will give 1st correct answer with explaination will rewarded as 5 stars and brainliest and lots of thanks... urgent​

Answer 1

Answer:

$\alpha + \beta = \frac{5}{4}$

$\alpha \beta = \frac{ - 1}{4}$

$\alpha {}^{2} + { \beta }^{2} =$

Step-by-step explanation:

therefore

$( \alpha + \beta ) {}^{2} = \alpha {}^{2} + { \beta }^{2} + 2 \alpha \beta$

substitute the value

${ \alpha }^{2} + { \beta }^{2} - \frac{1}{2}$

therefore

${ \alpha }^{2} + { \beta }^{2} = \frac{1}{2}$
