Question

answer this plz I am having pre board 3 today plz quick

Answer 1

for equation given have real roots
it's discriminant =0
here
a=2p+1
b=-(7p+2)
c=(7p-3)
$d = 0 \\ \sqrt{ { (- (7p + 2))}^{2} - 4(7p - 3)(2p + 1} = 0 \\ (7p + 2) {}^{2} = 4(7p - 3)(2p + 1) \\ solve \: this \: u \: will \: get \: p$
