​

Answer 1

Solution:

》2x² + 6 = -7x .... is the given quadratic equation

》2x² + 7x + 6 = 0

》2x² + 3x + 4x + 6 = 0

》x (2x + 3) + 2 (2x + 3) = 0

》(2x + 3) (x + 2) = 0

》x = -3/2 or -2

Therefore, the roots of the given quadratic equation are -3/2 and -2.

Answer 2

Answer:

x= $\frac{3}{2}$ or x=-2

Step-by-step explanation:

2$x^{2}$+7$x^{}$+6=0

2$x^{2}$+4$x^{}$+3$x^{}$+6=0

2$x^{}$($x^{}$+2)+3($x^{}$+2)=0

2$x^}$+3=0 or $x$+2=0

$x=\frac{3}{2}$ or -2

I hope u can understand it!
