Question

using quadratic formula, find the roots of the following equations 6x^2+7x_20=0​

Answer 1

Answer:

$\implies{6 {x}^{2} + 7x - 20=0} \\ \implies{6 {x}^{2} - 8x + 15x - 20=0} \\ \implies{2x(3x - 4) + 3(3x - 4)=0} \\ \implies{(2x + 3)(3x - 4) = 0} \\ \implies{2x + 3 = 0 \: \: or \: \: 3x - 4 = 0} \\ \pink{\boxed{\implies{x = - \: \frac{3}{2} \: \: or \: \: x = \frac{4}{3} }}}$
