Question

B Solve.
1) Write the following equations in the form ax2 + bx + c = 0.
(1) 2x² = 5x – 6 (2) x(x + 2) = 5​

Answer 1

Answer:

$2x^2-5x+6=0$, $x^2+2x-5=0$

Step-by-step explanation:

(1) $2x^2=5x-6$

$2x^2-(5x-6)=5x-6-(5x-6)$

∴$2x^2-5x+6=0$

(2) $x(x+2)=5$

$x*x+x*2-5=5-5$

∴$x^2+2x-5=0$

Answer 2

Answer:

ax²+bx+c=0

(1) 2x²=5x-6

2x²+(-5x)+6=0

here a=2, b=-5 and c=6

(2) x(x+2) =5

x²+2x+(-5) =0

here, a=1, b=2 and c= -5
