Question

5x2+13x+8=0 Solve using formula method​

Answer 1

☘️Solution:-

$→\;{\sf{5x²+13x+8 = 0}}$

$→\;{\sf{5x²+5x+8x+8 = 0}}$

$→\;{\sf{5x(x+1)+8(x+1) = 0}}$

$→\;{\sf{(5x+8)(x+1) = 0}}$

$→\;{\sf{x = \Large{\red{\bold-1\;\&\;\frac{-8}{5}}}}}$

• Roots of QE are -1 or -8/5

Answer 2

Answer:

$\huge\sf\red{Your \: Question}$

$5x ^{2} + 13x + 8 = 0 \\ \\ \\ \\ \\ \\ \\ by \: middle \: term \: splitting\\ 5x {}^{2} + 5x + 8x + 8 = 0 \\ \ 5x (x + 1)8(x + 1) = 0 \\ (5x + 8) (x + 1) = 0 \\ (x + 1) = 0 \\ (5x + 8) = 0 \\ therefore \: we \: get \: \ \: x = - 1 \: \\ x = \frac{ - 8}{5}$
