    Step-by-step explanation:

    a)Givenequation:x2−79=x2+9x+1

    /* subtract bothsides of the equation by x², we get */

    \implies x^{2} – 79 – x^{2} = x^{2}+9x+1 – x^{2}⟹x2−79−x2=x2+9x+1−x2

    \implies -79 = 9x + 1⟹−79=9x+1

    So, it \:is \:a \: Linear \: equationSo,itisaLinearequation

    b) Given \: 12x^{2} – 7 = 0b)Given12x2−7=0

    \blue { ( Degree \: of \: the\: equation \:is \: 2 )}(Degreeoftheequationis2)

    \green {So, it \:is \:a \: Quadratic\: equation.}So,itisaQuadraticequation.

    c) Given \: equation : 3x^{2}+11x+14=x(3x+5x)c)Givenequation:3×2+11x+14=x(3x+5x)

    \implies 3x^{2}+11x+14= x\times 8x⟹3×2+11x+14=x×8x

    \implies 3x^{2}+10x+14= 8x^{2}⟹3×2+10x+14=8×2

    \implies 3x^{2}+10x+14-8x^{2}=0⟹3×2+10x+14−8×2=0

    \implies -5x^{2}+10x+14=0⟹−5×2+10x+14=0

    \blue { ( Degree \: of \: the\: equation \:is \: 2 )}(Degreeoftheequationis2)

    \green {So, it \:is \:a \: Quadratic\: equation.}So,itisaQuadraticequation.

    d) Given \: equation : -x^{2}+11x-18 = 0d)Givenequation:−x2+11x−18=0

    \blue { ( Degree \: of \: the\: equation \:is \: 2 )}(Degreeoftheequationis2)

    \green {So, it \:is \:a \: Quadratic\: equation.}So,itisaQuadraticequation.
