Question

Solve the equation a) 5x-7/2=x(4+3x)

Answer 1

Answer:

Step-by-step explanation:

5x -7/2 = x(4+3x) {take LCM in next step}

2(5x) +(-7) /2 = x(3x+4)

2×5x-7/2 = x(3x+4)

10x-7/2 = x(3x+4)

10x-7/2=x×3x+x×4

10x-7/2=3x^2+4x {3x^2 , i.e.x to the power 2}

10x-7=2(3x^2+4x)

10x-7=2×3x^2+2×4x

10x-7=6x^2+8x

(10x-7) +(-6x^2-8x) =(6x^2+8x) +(6x^2-8x)

10x-7-6x^2-8x=6x^2+8x-6x^2-8x

10x-8x-6x^2-7=6x^2-6x^2+8x-8x

2x-6x^2-7=0, or

6x^2-2x+7=0

I hope this will help u
