The solutions of the equation [tex]7x\left( {x + 1.8} \right)[/tex] are [tex]\boxed{x = 0}[/tex] and [tex]\boxed{x = 1.8}.[/tex]
Further explanation:
Explanation:
The equation can be expressed as follows,
[tex]\begin{aligned}P\left( x \right)& = 7x\left( {x + 1.8} \right)\\&= 7{x^2} + 12.6\\\end{aligned}[/tex]
Degree is defined as the highest power of the polynomial function.
The given quadratic equation has 2 solutions.
Solve the equation [tex]7x\left( {x + 1.8} \right)[/tex] to obtain the value of x.
[tex]\begin{aligned}7x\left( {x + 1.8} \right) &= 0\\7x &= 0{\text{ or }}x + 1.8 &= 0\\x &= 0{\text{ or }x &=- 1.8 \\\end{aligned}[/tex]
The solutions of the equation [tex]7x\left( {x + 1.8} \right)[/tex] are [tex]\boxed{x = 0}[/tex] and [tex]\boxed{x = 1.8}.[/tex]
